Symposium on the Use ofCentrifuge Modelingin Earthquake Hazards Mitigation

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动态离心机模型在地震减灾研究中的使用。这些应用包括在地震引起的地面运动期间导致土体破坏的机制，以及用于分析这些条件下的土和土-结构相互作用的动力特性的技术验证。土工离心机模型试验用于模拟重力效应很重要的情况下的地球重力效应；这里所考虑的例子发生在土体的变形中。最近的离心机模型试验证实或扩大了土工离心机模型试验在地震工程研究中的应用；即研究含可液化土坝的地震反应、土坝的基础运动试验、土体的液化特性、流滑机理、加筋土路堤的稳定性、土-桩相互作用、土-桩-建筑物相互作用。这次研讨会的目的是向地震工程界迅速介绍这些成果。讲师是积极参与开发这些新技术的研究人员。

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.
