摘要
为研究深基坑施工期间地下连续墙支护结构的抗震稳定性,利用振动台进行了一系列小比尺模型试验,通过输入不同峰值加速度的汶川地震波,测试了不同施工阶段和不同插入比地下连续墙结构的动位移和加速度响应,系统研究了地震作用下,地下连续墙基坑支护结构在不同施工阶段的地震反应特性和地连墙不同插入比对基坑抗震稳定性的影响,为地震区地下连续墙基坑支护结构的设计和施工提供参考.
In order to study the seismic stability of underground continuous wall supporting structure during the construction of deep foundation,a series of small-scale model tests were made by using shaking table.The dynamic displacement and acceleration response of underground continuous wall structure were tested in different construction stages and different insert ratios by entering different peak acceleration of Wenchuan earthquake waves,and the seismic response characteristics of underground continuous wall structure at various construction stages and the impact to seismic stability of the pit under earthquake were systematically studied,which could offer references for the design and construction of underground continuous wall supporting structure in earthquake zone.
