US-Japan Seminar on Site Response and Ground Failure During Earthquakes/June 1993/No California

该奖项支持12名美国科学家参加将于1993年6月7日至9日在北加州举行的关于地震期间现场反应和地面破坏的美日研讨会。联合组织者是加州大学戴维斯分校的I.M. Idriss教授和东京大学的石原健二教授。研讨会的目的是交流有关岩土地震工程方面的资料，例如沙质土壤的液化和液化的后果，以及软土层下的土壤场地的反应，软土层可以放大地震运动（特别是在长期范围内），从而对所建的结构和其他设施造成额外的危害在这样的地点。研讨会将集中讨论地面反应和放大效应的最新进展、场地特征、地面破坏（例如洛马普里塔地震的历史案例）以及液化引起的流动破坏和变形的分析。参与者包括一些年轻的研究人员和一些已经与日本科学家建立了密切合作关系的科学家。这次研讨会是一个有价值的一步，继续努力了解和纳入设计和实践，措施，以减轻地震的影响，强烈的地面震动，表现在现场反应和地面破坏。

This award supports the participation of 12 U.S. scientists in a U.S.-Japan Seminar on Site Response and Ground Failure during Earthquakes, to be held June 7-9, 1993 in Northern California. The co-organizers are Professor I.M. Idriss, University of California, Davis, and Professor Kenji Ishihara, University of Tokyo. The objective of the seminar is to exchange information on geotechnical earthquake engineering in such areas as liquefaction in sandy soils and the consequences of liquefaction and the response of soil sites underlain by layers of soft soils that can amplify the seismic motions (particularly in the long period range) and thus pose additional hazards to structures and other facilities constructed at such sites. Seminar sessions will focus on the latest advances in ground response and amplification effects, site characterization, ground failure (case histories such as the Loma Prieta Earthquake), and analysis of liquefaction-induced flow failures and deformations. The participants include some young researchers and some scientists who have already formed close collaborative ties with Japanese scientists. This seminar is a valuable step in the continuing efforts to understand and to incorporate into design and practice, measures to mitigate the effects of earthquake strong ground shaking as manifest through site response and ground failure.
