The registered company address is: 152 Beach Road, #21-01/04 Gateway East, Singapore 189721, Singapore Foreword This is a book about highway engineering structural design and construction technology, which is very professional, and is the authors’ summary of decades of practical experience and his understanding of theoretical thinking. The author Zhu Hanhuaisaseniorengineerwithrichexperienceinengineeringdesign,andhehas accumulated a large number of cases in years of practice on highways in Sichuan and Tibet, where the design and construction techniques are very difficult; author Shi Lei, graduated from Zhejiang University, has been building roads and bridges inSichuanandTibetformorethan20years,andhasrichexperienceinconstruction and unique theoretical insight. The joint work of both of them, with theory and practice, problem-centered, targeted and down-to-earth, can be a practical manual for technical personnel in highway engineering structural design and construction. To tell the truth, I don’t understand most of the contents of this book. I don’t understand engineering technology, let alone the design and construction of high- wayengineeringstructures.ThereasonwhyIamwritingtheprefacetothisbookis that I sincerely admire the two authors’ spirit of consciously using philosophical methodology to solve problems of engineering technology, and I want to support andencouragethisexploration.Thetwoauthors,onefromComradeMaoZedong’s hometown and the other from Comrade Deng Xiaoping’s hometown, were full of reverenceforthesetwogreatmenfromanearlyage.Theylikedreadingtheirbooks andlearningtheirspiritualstyleandwaysoflifewhentheywereyoung.Theyread through the Selected Works of Mao Zedong (Volume 1–4) and the Selected Works of Deng Xiaoping (Volume 1–3), especially inspired by the world outlook and methodologyofthetwogreatmeninsolvingmajorproblemsinChina’srevolution, construction and reform by applying Marxist philosophy. They get inspiration and reference from it, and want to use the Marxist world outlook and methodology to solve the problems in their work, that is, the design and construction of highway engineering structures. Theauthorsofthisbook,lookingatthesimilarities anddifferencesbetweenthe two modes of thinking in Chinese and Western philosophy and their complemen- tation, think that in the field of engineering technology, the advantages of the two modes of thinking should also be absorbed to avoid their shortcomings. For v vi Foreword example, Western philosophy pays attention to analysis and synthesis, induction and deduction, while Chinese philosophy pays attention to integration and con- nection, intuition and understanding, etc., which can all be applied to highway engineering structural design and construction. The world outlook and methodol- ogy of Marxist philosophy are more instructive. For example, both “two-point theory”and“keytheory”arerequired;notonlytograspthemaincontradictionsand majoraspectsofthosecontradictions,butalsotocoverthewholetoachieveagood overall balance. The authors believe that simplification of complex problems is an important method for mechanical analysis of engineering problems, but to realize that, the unity of overall control and the control of details should be achieved. Simplification of complex problems is conditional, and maintaining a stable equi- librium of the system is the key. Theauthorsofthisbookalsopayattentiontoabsorbingspiritual nutrients from the red culture. For example, they extracted a method of comprehensive analysis fromComradeMaoZedong’sOnProtractedWar,consideredthatthe“threemagic weapons”oftheCommunistPartyofChina,thatistheunitedfront,armedstruggle and party building, can be used by analogy and reference in the structural design and construction of highway projects; Comrade Deng Xiaoping’s “emancipating the mind and seeking truth from facts” can also become the ideological line fol- lowed in engineering design, etc. What is commendable is that the fifth chapter, “Application of Typical Engineering”, and the sixth chapter, “Analysis of Typical Problems”, of the book analyze a large number of problems and cases in the structural design and con- struction of highway engineering, and contain the authors’ unique line of thought and suggestions, which fully embody the “living soul” of the dialectics of “cir- cumstances alter cases” and “everything depends on time and place”. Only the colleagues engaged in structural design and construction of highway engineering can realize the mystery and benefit from it. The last part of the book includes Academician Pan Jiazheng’s article PhilosophicalThinkingintheConstructionofWaterConservationProjectsandmy article DialecticsofReformandOpening-up.Ithinktheauthorsmean tousethese two articles as evidence to illustrate the fact that large-scale projects cannot work without philosophical thinking and guidance. Academician Pan’s article explains that the construction of water conservation projects should be guided by a philo- sophical world outlook and methodology. My article explains that the reform and opening-up is also a big project and cannot be separated from the guidance of Marxist dialectical materialism and historical materialism. This article of mine is myexperienceoflearningfromGeneralSecretaryXiJinping’simportantstatement oncomprehensivelydeepeningthereform.GeneralSecretaryXiJinpinghassetan example for us in the process of leading the comprehensive deepening of the reform, and he is a model of learning philosophy and using philosophy. Xi Jinping’s Thought on Socialism with Chinese Characteristics for a New Era is the latest development of Marxism, and is Marxism in the twenty-first century. Foreword vii TheinspirationfrommyreadingofthisbookisthataMarxistworldoutlookand methodology can not only guide the governance of the country, but also guide engineeringtechnology.Engineeringandtechnicalpersonnelshouldnotonlyhave excellent professional qualities, but they should also have a basic philosophical background.Usingacorrectworldoutlookandmethodologyasguidance,theywill often get more with less and achieve greater success. Once again, I would liketo paytributetothetwo engineers and techniciansfor their valuable philosophical exploration. Beijing, China Feng Jun Feng Jun is a philosopher, professor and doctoral supervisor, who has successively held the following positions: Vice President of Renmin University of China and Dean of the School of Philosophy, Chairman of the Chinese Society of the History of Foreign Philosophy, Deputy ChairmanofthePhilosophyTeachingSteeringCommitteeoftheMinistryofEducation,Executive Vice President of the China Executive Leadership Academy in Pudong, Deputy Director of the CentralPartyHistoryResearchOffice,andExecutiveVicePresidentoftheChineseCommunist PartyHistoricalSociety,etc. Preface Comprehensive statistical data show that among the death toll of various incidents ofcollapseincivilengineering,undergroundworksaccountfor32.6%,foundation pit excavation and retaining wall collapse account for 23.9%, the collapse of temporary facilities and supporting elements account for 32.6%, and structural collapse such as road bridges account for 9.9%, but the number of critically damaged bridges with a service life of less than 30 years accounts for 64% of the total number of critically damaged bridges, even though structural defects such as road bridges in developed countries in Europe and the United States also account for 11%. The root cause of the above high incidence of engineering damage is the problem of metastable equilibrium of traffic engineering structures. In addition to theengineeringenvironmentalconditionsandhumanfactors,theexistingtheoryof equilibrium and stability of engineering structures has implicit “deformation coordination” restrictions in its application. However, when some engineering structures are stressed, their material properties, microstructure, constitutive rela- tionship, integration and force transfer path will change, which does not meet the implicit constraints of deformation coordination theory. If we regard “deformation coordination” asa theoreticalproblemand needtoinnovate thetheory and rebuild the system, we will complicate the engineering problem and have limited effect in solving the actual engineering problem. Although it is complicated to deduce, the essence of solving the problem is still the control method. If “deformation coor- dination” is regarded as the problem of control method, as long as the technology and structure are innovated, the engineering problem will be simplified, and the effect of solving the actual engineering problem by using the existing theory of equilibrium and stability of engineering structures is better. Both of them have the same goal of solving the problem, but theprocess and methodare different, that is to say, the state of stress and deformation of the control engineering structure is different.Theformercomplicatesthesimpleproblemwhilethelattersimplifiesthe complex problem. From the perspective of methodology and solving the practical engineering problems, it is more appropriate to regard “deformation coordination” as the problem of control method. In view of unfavorable structures or composite engineering structures such as flexible bending members, broken surrounding ix x Preface rocks, soft soil foundation, etc., the application of engineering mechanics to solve structural problems of engineering should be studied on the premise offollowing methodology, and the problems that may occur in actual engineering should be exposed to the research and test links, so as to solve them in the design and construction links, avoid problems of quality and even of safety in actual engi- neering use, and ensure the safety of people’s lives and property. Chairman Mao Zedong pointed out the construction of Beijing Metro Line 1: “carefulindesign,carefulinconstruction,intheconstructionprocesstherewillbea lotofmistakes,failures,weshouldalwayspayattentiontocorrectingthem”,which isanexampleofusingphilosophytoguideengineering;ComradeDengXiaoping’s guidance on reform and opening-up calls for “emancipating the mind and seeking truthfromfacts”,whichisbothanideologicallineanddialectics.BothMaoZedong and Deng Xiaoping were masters of “learning war in war”. Whether it is war or revolution, construction or reform, they cannot be separated from materialist dialectics.Inventionsinscienceandtechnologyneedtolearnandmastermaterialist dialectics. The greatest enemy of innovation is becoming accustomed to it. Technological progress and construction complement each other. It is difficult to develop technology without construction projects. Inspired by the article Philosophical Thinking in the Construction of Water Conservation Projects of Pan Jiazheng and guided by Feng Jun, professor of philosophy, the authors of this book try to discuss the practical experience of structural design and construction technology of highway engineering from the perspective of methodology. It is divided into three parts: the methodology of law andtheory,themethodoftheanalysisofcomprehensiveresearch,thesimplification ofcomplexproblems,andtheapplicationoftypicalengineeringandthesuggestion of problems. At the end, there are guides for facilitating the personnel of engi- neering construction in using philosophical methods to guide engineering con- struction, but not limited to philosophy to guide engineering discussion. This book is the authors’ attempt at writing about the problem of the method- ology for the construction of highway engineering structural design, there will inevitably appear various defects and mistakes, and all readers are welcome to criticize and correct!
