| 摘 要： | 提出了应用隧道施工监测的随机值，采用蒙特一卡罗（Ｍｏｎｔｅ－Ｃａｒｌｏ）有限元随机反分析以反推地层参数和初始地应力分布的方法。反推参数不仅给出其均值，还给出参数的方差及分布类型，为地下结构稳定性和可靠性分析提供必要数据。为检验所提的反分析方法对工程的实用性，文中给出了一个实例。

| Abstract: | A back analysis by Monte-Carlo element method is propgsed to estimate field geotechnicalparameters according to the measured displacements in tunnelling. The results of back analysis give samplemeans,variances and their types distribution which are necessary in estimating stability and reliability oftunnelling.A case study on a tunnelling is presented to illustrate the effectiveness of this method. |
