摘　　要：对目前基坑开挖卸荷回弹量的各种计算方法进行了分析,提出了比较适用的在正常施工状态下考虑基坑开挖面积、深度、围护结构插入深度的估算方法,并综合考虑了其他因素的影响,用实例证明该方法具有较大的实用价值。In this paper various current calculating methods of the foundation pit resilience during excavation are analyzed. And it is proposed the appropriate estimated formula considering the problems of pit resilience under different eireumstanes including execution shapes and depths, depth of retaining structure. Finally, the methods are proved that it has great value through examples.
