The objective of this symposium is to expose other researchers, agencies, industry, and advanced graduate students to the use of dynamic centrifuge modeling in the study of earthquake hazard mitigation. These applications include the mechanisms causing failure in soil masses during earthquake- induced ground motions, and the verification of techniques used to analyze the dynamic behavior of soil and soil-structure interaction under these conditions. Geotechnical centrifuge model experiments are used to simulate the effects of the earth's gravity for cases where gravity effects are important; the examples considered here occur in the deformation of soil masses. Recent centrifuge model tests have verified or expanded upon the use of geotechnical centrifuge model tests in earthquake engineering research; namely to study the earthquake response of dams containing liquefiable soils, the base motion tests in earth dams, the liquefaction behavior of soil masses, the mechanism of flow slides, the stability of reinforced earth embankments, soil-pile interaction, and soil-pile-building interaction. The objective of this workshop is to present these results quickly to the earthquake engineering community. The lecturers are researchers actively involved in developing these new techniques.

本次研讨会的目的是让其他研究人员、机构、行业和高级研究生了解在地震减灾研究中使用动态离心机建模。这些应用包括在地震引起的地面运动中引起土体破坏的机制，并验证了在这些条件下用于分析土壤动力特性和土-结构相互作用的技术。在重力作用重要的情况下，采用土工离心机模型实验来模拟地球重力的影响；这里考虑的例子发生在土体的变形中。最近的离心模型试验验证或扩展了岩土离心模型试验在地震工程研究中的应用；即研究含液化土坝的地震反应、土坝地基运动试验、土体液化特性、流滑机理、加筋土路堤稳定性、土桩相互作用、以及土-桩-建筑的相互作用。这次研讨会的目的是向地震工程界迅速介绍这些结果。讲师是积极参与开发这些新技术的研究人员。
