U.S.-Japan Joint Seminar: Seismic Disaster Mitigation in Urban Area by Geotechnical Engineering (Anchorage, Alaska May 21-22, 2002)

[01:53 . 46]该奖项支持美国科学家参加将于2002年5月21日至22日在阿拉斯加州安克雷奇举行的关于通过岩土工程减轻城市地区地震灾害的美日研讨会。联合组织者是加州大学戴维斯分校的Ross Boulanger教授和日本东京大学的Ikuo Towhata教授。地震可以通过多种方式摧毁主要城市地区，包括对人口构成的危害，生命线系统和服务的中断，以及对地区，州或国家的经济影响。从最近的大地震中，我们对地震危害及其缓解的认识不断取得进展。最近发生在1999年的Chi-Chi（台湾）、1999年的Kocaeli（土耳其）和2000年的Bhuj地震对这些国家的城市及其周边地区的民用基础设施造成了巨大的破坏。美国和日本独立派出的侦察小组调查了这些灾难。将讨论这些灾害的岩土工程方面，包括液化、地面变形、地基失效、滑坡和地面破裂对民用基础设施（如生命线、港口、建筑物、运输系统）的影响。研讨会的目的是促进我们的理解和能力的进步，以减轻地震灾害的岩土方面。关于这些主题的讨论将包括：1)开发减轻这些危害的新工程技术；2)确定应优先解决的问题；3)分享最新的研究成果，以提高我们对这些类型的危害的理解和预测能力，并有效地规划减灾工作。两国的一些研究人员将继续对重要地点进行更彻底的调查，从中吸取教训，从而提高我们对这些危害的认识。该项目通过博士后和一名研究生的参与来推进国际人力资源。通过思想和技术的交流，该项目将扩大我们的基础知识基础，促进国际了解与合作。研究人员计划在岩土工程建模中心的网站（http://cgm.engr.ucdavis.edu/）上公布研讨会的结果。

0135346BoulangerThis award supports the participation of American scientists in a U.S.-Japan seminar on seismic disaster mitigation in urban areas by geotechnical engineering to be held in Anchorage, Alaska from May 21-22, 2002. The co-organizers are Professor Ross Boulanger of the University of California, Davis and Professor Ikuo Towhata at the University of Tokyo in Japan. Earthquakes can devastate major urban areas in a number of ways, including through the hazards posed to the population, the disruption of lifeline systems and services, and the economic impacts on the region, state, or nation. Advances in our understanding of seismic hazards and their mitigation continue to be learned from recent large earthquakes. Recently the 1999 Chi-Chi (Taiwan), 1999 Kocaeli (Turkey), and 2000 Bhuj earthquakes caused tremendous damage to the civil infrastructure in and around urban areas in those countries. Reconnaissance teams sent independently from the U.S. and Japan investigated these disasters. Geotechnical aspects of these disasters will be discussed, including the effects of liquefaction, ground deformations, foundation failures, landslides, and surface ruptures on civil infrastructure (e.g., lifelines, ports and harbors, buildings, transportation systems). The objective of the seminar is to facilitate advancement of our understanding and ability to mitigate geotechnical aspects of seismic disasters. Discussions on these subjects will include: 1) development of new engineering techniques for mitigation of these hazards; 2) identification of those problems that should be solved with the highest priority; and 3) sharing the most recent results of research to advance our understanding of, and ability to predict, these types of hazards and effectively plan mitigation efforts.A number of researchers in both countries will continue to more thoroughly investigate important sites for lessons that can advance our understanding of these hazards. The project advances international human resources through the participation of postdocs and a graduate student. Through the exchange of ideas and technology, this project will broaden our base of basic knowledge and promote international understanding and cooperation. The researchers plan to publish results of the seminar proceedings on their web site at the Center for Geotechnical Modeling (http://cgm.engr.ucdavis.edu/).
