摘要
基底隆起导致墙后土体位移是基坑失稳的模式之一。本文在分析了引起基底隆起的因素之后，对土性参数的变异特性和分布特征进行了研究。结合上海地区的工程实践，采用极限状态设计方法，对引起基底隆起的因素进行了评价。
In the braced excavation , one of the models of foundation pit destabilization. is the basal heave as causing of the displacement and settsettling of the soil behind wall. The paper , after studying the vartiabibty ,correlation and distribu- tion characteristics of parameters of soil , applying the limit state method , evaluates the stability against basal heave of foundation pit , and analyzes the factors causing the basal heave.
