摘要

以饱和砂土液化后场地失效模式特征与场地失效时群桩基础地震反应破坏机理为研究目的

依托中国建筑科学研究院大型模拟地震振动台系统

开展可液化场地、非液化场地在水平地震动激励下桩-土-结构动力相互作用动力体系大型振动台系列试验。基于本次系列试验研究对象以及试验目的

阐述了系列试验中动力模型体系相似比设计的基本原则、地基的制备、模型结构制作、各个种类传感器的选择与布设、输入地震记录的选取与工况安排等内容

介绍了阵列式位移计、非接触式位移动态采集系统等新型传感测试设备

并对所采用的层状单向剪切模型土箱设计合理性与科学性进行了验证。由之后的试验结果可知

本次系列试验设计方案是合理、可靠的

层状剪切模型箱的"模型箱效应"很小。

Abstract

To study on the failure model of sites after sand liquefaction and the failure mechanism of seismic response of piles foundation

and relying on the Large-scale Simulated Seismic Shaking Table System of China Academy of Architectural Sciences

liquefiable and non-liquefiable sites large-scale shaking table tests of piles-soil-structure dynamic interaction system under horizontal earthquake excitation were carried out.According to the research objective and purpose of this series of large-scale shaking table tests

this paper expounds the basic principles of similarity ratio design of dynamic model system in the test series

preparation of the sites

design of model structures

selection and arrangement of various sensors

input seismic records and the load events.The new sensor testing instruments

such as the Shape Acceleration Array

and the non-contact displacement measuring system

are introduced.Besides

the rationality and scientific nature of the soil box for laminar and one-direction shear tests have been verified.
