Firstly, Optimization back analysis of parameters is carried out based on the datas of practical measure, because in this project the parameters of concrete neither testing nor practical datas.

由于本工程混凝土材料各项物性参数即无试验数据又无量测数据，所以，本文首先结合实际测量资料对其进行了参数的优化反演。

With the measured data, the parameters of equivalent circle zone can be obtained by back analysis of soil displacement.

在有实测位移的情况下，可运用位移反分析法较准确地获取等代层的参数。
