筒仓结构随着其规模越来越大,对基础和地基的要求也越来越高,尤其是湿陷性黄土地基的承载力和沉降量的要求也更加严格.本文运用有限元软件ABAQUS,对湿陷性有限元模拟与处理方法进行了深入的分析,结合工程实例着重研究了灰土垫层处理厚度对地基沉降与基底反力的影响,确定了灰土垫层的有效处理深度.%As the scale is wider and wider,silo structure has higher requirement for the foundation and basis,especially the bearing capacity and settlement of collapsible loess foundation is more stringent.This paper in-depth analysis on the finite element simulation and treatment of collapsible loess by using the finite element software ABAQUS,Finally,analyzed the affection of different lime soil cushion thickness to the foundation settlement and the basal reaction force,determine the effective depth.
