摘　　要：基于工程实例,提出基坑拆撑后在竖向支护构件的基础底板处设置扶壁,假定扶壁与支护构件组成悬臂二阶柱,进行柱顶水平位移和受弯承载力验算,计算结果满足基坑变形、强度的控制要求。Based on engineering examples , putting the buttress on the baseboard of vertical supporting components after foundation pit bracing substitution has been raised up .And it is supposed buttress and supporting components are made up cantilevered two -step column, horizontal displacement and flexural capacity have been calculated , and the results satisfy the control requirement of transformation and strength of foundation pit .

关 键 词：基坑换撑 扶壁 悬臂二阶柱 水平控制位移 受弯承载力
