9810678 Kutter centrifuge model testing is an important tool for earthquake engineers to help understand the engineering deformation and failure of soils and foundations and their interaction with structures. Physical models of these failure and deformation problems can be constructed and tested while they spin on a centrifuge. The centrifuge acceleration field increased the "self weight" of models so that stresses in the model are similar to those in typical prototypes. Because soils have nonlinear material properties, the similarity of stresses in model and prototype greatly enhances the accuracy of the model tests. The centrifuge is an extremely valuable tool for systematic studies of the effects of earthquakes on soils and soil-structure interaction. The new geotechnical centrifuge in Hong Kong will provide a unique opportunity for engineers to obtain data to study the effects of two directional (2-D) shaking on soils and soil- structure systems. This project will organize an international symposium to allow researchers in Asia and the U.S. and other parts of the world to exchange experiences in soil dynamics research in general and centrifuge model testing in particular. The workshop will open the possibility of future collaboration including the sharing of data and facilities and the planning of complementary research programs. The possibilities and plans for networking of the Hong Kong centrifuge with U.S. and international geotechnical earthquake engineering facilities, as an extension of the MRE/ 15 HPS concept, will also be discussed in the symposium. ***

9810678 Kutter离心机模型测试是地震工程师的重要工具，可以帮助了解土壤和基础的工程变形和失败及其与结构的相互作用。 这些故障和变形问题的物理模型可以在离心机上旋转时构建和测试。 离心机加速场增加了模型的“自重”，因此模型中的应力与典型原型中的应力相似。 由于土壤具有非线性材料特性，因此模型和原型中应力的相似性大大提高了模型测试的准确性。 离心机是系统研究地震对土壤和土壤结构相互作用的影响的极为有价值的工具。 香港新的岩土工程离心机将为工程师提供一个独特的机会，以获取数据来研究两个方向性（2-D）摇动对土壤和土壤结构系统的影响。 该项目将组织一次国际研讨会，以允许亚洲，美国和世界其他地区的研究人员尤其是一般和离心机模型测试来交换土壤动态研究的经验。 研讨会将开放未来合作的可能性，包括共享数据和设施以及补充研究计划的计划。 香港与美国和国际岩土技术地震工程设施的网络网络的可能性和计划，作为MRE/ 15 HPS概念的扩展，也将在研讨会上进行讨论。 ***
