Preface This book consists of 25 chapters focusing on the latest developments in reinforced soil technology. These chapters address geotechnical earthquake issues, as well as applications and case histories from several countries. Several chapters are based on presentations given during the Columbia Workshop (the International Workshop on Seismic Design of R einforced Soil Structures). The Columbia Workshop was part of a project called "Seismic Perfor mance and Design of Reinforced Soil Structures with Reference to Lessons Learned from the 1999 Earthquakes of T aiwan and Turkey," which was funded by the Geotechnical Program of the National Science Foundation (PIs: Hoe I. Ling and Dov Leshchinsky; Grant No. CMS-0084449; Program Director: Dr. Richard J. Fragaszy). The workshop was a I! - day event featuring speakers and panelists from leading institutions in the United States, Canada, Japan, Taiwan, and T urkey. A bout 4 0 r esearchers and engineers a ttended t he workshop. The study of seismic performance of reinforced soil structures has received much attention since the 1995 Kobe earthquake, and especially since the failures reported during the 1999 Ji-Ji earthquake in Taiwan. In recent years, the National Science Foundation and some state departments of t ransportation have initiated r esearch projects o n this subject. In Japan, works were initiated by various groups of r esearchers at academic institutions and government agencies. However, there has been rather limited discussion among the researchers working on this subject. Therefore, the need arose to document lessons learned from past experience, to share knowledge about ongoing achievements in this field, and to allow for intensive discussion by identifying problems noted and data gathered. iii iv Preface The Columbia Workshop was held at the Faculty House of Columbia University on October 30 and 31, 2000. It was inaugurated by Professor Rimas Vaiacitis, Chair of the Department of Civil Engineering and Engineering Mechanics, Columbia U niversity. The first day consisted of 1 4 invited presenta tions. (Information on the meeting, including abstracts and representative publications of the presenters, is also available at http://www.civil.columbia. edul-ling/taiwan.) Following invited presentations, three discussion sessions were organized, focusing on design issues, testing and experimental studies, and numerical methods and modeling. These sessions were chaired by Jerry DiMaggio of F HWA , Furnio Tatsuoka of t he University of T okyo, and Andrew Whittle of MIT. The workshop was subsidized by the Federal Highway Administration through the arrangement of Mr. Mike Adams, with matching funds from the Dean's O ffice of t he School of E ngineering and Applied Science at Columbia University. The c ase h istories presented h ere help to advance the state of t he art i n this field; the failures documented should not discourage us from using existing technologies or developing new technologies. The knowledge shared in this workshop led to the organizing of two special technical sessions during the International Conference on Geosynthetics in Nice, France, in September 2002. The contributions of all authors herein are greatly appreciated. We acknowledge the efforts of P rofessor Vaicaitis, especially during the editing of the book. Hoe Ling is supported by an NSF Career Award (CMS-0092739; Program Director: Dr. Clifford Astill). Last but not least, we express sincere thanks to the editors at Marcel Dekker, Inc., especially Mr. Michael Deters, for his efforts in making this book a reality. Hoe l.
