U.S.-Japan Joint Seminar: Soil Behavior and Ground Response for Hazard Assessment during Earthquakes

该奖项支持美国科学家参加将于1997年7月1日至2日在日本北海道举行的关于地震期间土壤行为和地面反应对灾害评估的美日研讨会。联合组织者是加州大学戴维斯分校的i.m.伊德里斯教授和日本东京科学大学的石原健二教授。本次研讨会将提供一个论坛，汇集以下方面的最新信息：1)无黏性土壤的液化，2)黏性土壤的破坏，以及3)软黏性土层或在受到震动时易于液化的土层下的土壤场地的反应。在地震中，由于无黏性土壤的液化和黏性土壤的过度应力引起的地面破坏会对港口、建筑物、桥梁和其他民用基础设施造成重大破坏。了解砂土的液化和粘性土在地震作用下的破坏是制定设计指南以减轻地震损害的重要第一步。减少自然灾害是美日合作的一个优先领域。与该领域的日本专家交流想法和数据将使美国参与者能够推进自己的工作，并为未来的合作项目奠定基础。＊＊＊

9603028 Idriss This award supports the participation of American scientists in a U.S.-Japan seminar on Soil Behavior and Ground Response for Hazard Assessment During Earthquakes to be held in Hokkaido, Japan from July 1-2, 1997. The co-organizers are Professors I. M. Idriss of the University of California at Davis and Kenji Ishihara of the Science University of Tokyo in Japan. This seminar will provide a forum for bringing together up-to-date information on 1) liquefaction in cohesionless soils, 2) the failure of cohesive soils, and 3) the response of soil sites underlain by layers of soft cohesive soils or layers that tend to liquefy when subjected to shaking. Ground failure during earthquakes, as caused by liquefaction in cohesionless soils and over-stressing of cohesive soils, results in major damage to ports and harbors, buildings, bridges, and other civil infrastructure facilities. Gaining an understanding of liquefaction in sandy soils and failure in cohesive soils subjected to earthquakes is an important first step in developing design guidelines to mitigate the damages of earthquakes. Natural disaster reduction is a priority area for U.S.-Japan Cooperation. The exchange of ideas and data with Japanese experts in this field will enable U.S. participants to advance their own work, and will set the stage for future collaborative projects. ***
