摘要
本文将岩体弹模、泊松比、比重等作为随机变量,推导了岩体结构分析的随机有限元公式。由随机有限元的结果可以进行大体积连续结构的可靠度分析。算例表明了材料参数的离散性对岩体可靠度的影响。
In this thesis,the deformation modulous,Poisson(?)atio, special gravity and strength parameter of(?)ock massesae teated as andom variables,and the formulae of stochastic finite element analysis for rock masses are derived.The eliability analyois of large scale continuous structure can be evaluatedby using the results of stochastic finite element analysis.The example shows that the imfluence of the dispersion of mate(?)ial parameters on stability reliability of rock masses is very important.
