摘要
由于基坑开挖过程中土体结构受到扰动，导致土体强度降低。可以根据实际监测结果，通过反分析的方法，推算出符合扰动后土体的各项计算参数，用以预测后续工况的变形与内力，从而对基坑的稳定性作出一种新的评价。
Disturbance of soil structure leads to the falling of soil strength. New calculation parameters of disturbed soil can bededuced from monitoring result through back-analysis. According to these new parameters. later internal force and deforma-tion can be predicted and the stability of excavation can be re-evaluated with new calculation parameters.
