Sincethattime,bothrockengineeringitselfandtheassociatedrockmechanicsresearch have increased in activity by leaps and bounds, so much so that it is difficult for an engineer or researcherto be aware of all the emerging developments, especially since theinformationiswidelyspreadinreports,magazines,journals,booksandtheinter- net. It is appropriate, if not essential, therefore that periodically an easily accessible structuredsurveyshouldbemadeofthecurrentlyavailableknowledge.Thus,weare most grateful to Professor Xia-Ting Feng and his team, and to the Taylor & Francis Group, for preparing this extensive 2017 “Rock Mechanics and Engineering” com- pendiumoutliningthestateoftheart—andwhichisapublicationfittingwellwithinthe Taylor&Francisportfolioofgroundengineeringrelatedtitles. There has previously only been one similar such survey, “Comprehensive Rock Engineering”, which was also published as a five-volume set but by Pergamon Press in 1993. Given the exponential increase in rock engineering related activities and research since that year, we must also congratulate Professor Feng and the publisher ontheproductionofthiscurrentfive-volumesurvey.Volumes1and2areconcerned with principles plus laboratory and field testing, i.e., understanding the subject and obtainingthekeyrockpropertyinformation.Volume3coversanalysis,modellingand design,i.e.,theproceduresbywhichonecanpredicttherockbehaviourinengineering practice. Then, Volume 4 describes engineering procedures and Volume 5 presents a varietyofcaseexamples,boththesevolumesillustrating‘howthingsaredone’.Hence, the volumes with their constituent chapters run through essentially the complete spectrumofrockmechanicsandrockengineeringknowledgeandassociatedactivities. Inlookingthroughthecontentsofthiscompendium,Iamparticularlypleasedthat Professor Feng has placed emphasis on the strength of rock, modelling rock failure, field testing and Underground Research Laboratories (URLs), numerical modelling methods—which have revolutionised the approach to rock engineering design—and theprogressionofexcavation,supportandmonitoring,togetherwithsupportingcase histories. These subjects, enhanced by the other contributions, are the essence of our subject of rock mechanics and rock engineering. To read through the chapters is not onlytounderstandthesubjectbutalsotocomprehendthestateofcurrentknowledge.
