摘　　要：根据湿陷性黄土的特性,基于现有的湿陷性黄土地基处理方法及其缺陷,在分析大厚度湿陷性黄土地区独特的工程地质环境基础上,提出灰土垫层与防渗膜相结合的联合地基处理方法,构建了大厚度湿陷性黄土场灰土垫层与防渗膜联合地基(整片处理),并针对工程要求,在对该联合地基初步设计基础上进行了力的相互作用和变形及效应研究。In this paper,according to the characteristics of collapsible loess,and based on existing approaches on loess and their defects,the foundation operation methodology combining with lime soil cushion and impervious membrane is proposed through applying analysis on the unique engineering geological environment of thick collapsible loess.The proposed methodology is extensively studied,and the composite foundation of lime soil cushion and impervious membrane in collapsible loess area with large thickness is developed.What's more,with considering the engineering requirements,and based on the preliminary design of the joint foundation of lime soil cushion and impervious membrane,the force mutual action,deformation and effect of joint foundation are studied.
