摘要

采用大型通用有限元程序ADINA，针对一例水泥土搅拌桩复合地基-基础-上部结构典型算例，建立了数学模型，并进行了有限元动力时程分析。计算模型中将水泥土搅拌桩和桩间土作为整体参与计算，复合土体和土体采用线性黏弹性动力本构模型，上部结构和基础采用线弹性本构模型，通过在边界设置阻尼器来模拟无限域中的动力人工边界。通过数值计算研究了复合土体模量、土体模量和加固深度对加固区和非加固区位移峰值、速度峰值和加速度峰值的影响，从而为水泥土搅拌桩复合地基抗震加固设计提供参考依据。

Abstract

The cement-soil mixing pile composite foundations are getting more and more application to construction engineering. However

the research on their response under dynamic loading

especially under earthquake loading

is quite limited. Now

the seismic response analysis in the time domain is performed with ADINA program

considering the interactions among soil

foundation and the superstructure. Based on these analyses

some conclusions which may be useful for aseismic design of this type composite foundations are drawn.
