第六届国际地震岩土工程大会综述

An Overview of the Sixth International Conference on Earthquake Geotechnical Engineering

第六届国际地震岩土工程大会于2015年11月1-4日在新西兰克莱斯特彻奇市召开。本文介绍了大会概况;阐述了大会设置的21个专题,并综述了场地效应和小区划,斜坡、河堤、大坝与废弃物填埋场,地震危险性与强地面运动,土壤液化与侧向扩展共4个重要专题分会的交流内容;通报了国际地震岩土工程及其问题技术委员会(TC203)全委会内容和决议事项;论述了相关领域的研究进展与亮点,包括新西兰坎特伯雷地震灾后重建催生了岩土工程共享数据库建设取得突破性进展;土壤液化与侧向扩展研究成为国际岩土地震工程一大热点研究领域;提出了在液化机理、液化势评价、液化后变形和基于性能的抗液化工程设计等方面需要进一步研究的重要问题;运动颗粒模拟方法实现了对斜坡破坏的全过程数值模拟;"Ishihara-Idriss-Finn演讲特别分会"成为本次会议一大亮点;2010-2011年新西兰坎特伯雷地震序列(CES)发生后,美国与新西兰开展了非常紧密的合作调查与研究工作,并在地震序列认识、灾害快速评估、确保稳健恢复的政策与规划分析等方面取得了多方受益的科学进展。

The sixth International Conference on Earthquake Geotechnical Engineering was held in Christchurch,New Zealand,from November 1to 4,2015.This study provides an overview of the conference.In the conference,21 oral session topics were introduced.We summarize the contents of the academic exchange particularly in four oral sessions：those addressing（1）site effect and microzonation;（2）slopes,embankments,dams,and landfills;（3）seismic hazards and strong ground motion;and（4）soil liquefaction and lateral spreading.We also report the contents and decisions of the Technical Committee on Earthquake Geotechnical Engineering and Associated Problems（TC203）of ISSMGE and evaluate research advances and highlights in relevant fields as follows：（1）a breakthrough in the development of a shared geotechnical engineering database for the rebuilding of Christchurch,New Zealand（NZ）,following the Canterbury earthquake sequence（CES）;（2）soil liquefaction and lateral spreading as the hottest issue in international earthquake geotechnical engineering;（3）the need to further study key scientific problems with respect to the liquefaction mechanism,the evaluation of the liquefaction potential,post-liquefaction deformation,and performance-based design in anti-liquefaction engineering;（4）the presentation of the moving particle simulation method for simulating the slope failure process;（5） ＂the special session of Ishihara-Idriss-Finn presentations＂ as a highlight of the conference;and（6）the close cooperation of the United States（US）with NZ,following the CES in 2010-2011,with respect to field investigation and research.Bilateral NZ-US collaborations for immediate response and long-term research have resulted in mutually beneficial scientific advancements for understanding the CES,achieving rapid damage assessment,and in policy and planning analysis to enable robust recovery.
