摘　　要：研究工作中正分析、反分析和原位观测资料分析均采用同一的确定性模型。用三维有限元与概率统计论对岩基的“等效变形参数”进行了反分析。评价了工程运行现状的安全度,对未发生事件的变位和安全度做了预报。The same deterministic model is used to conduct direct analysis,inverse analysis and the analysis of in situ observation data.Through the 3-D FEM and probability theory,the inversion analysis has been made on the equivalent deformation parameter of rock foundation.The degree of safety of the project in the present time is evaluated,and the deformation and degree of safety in the future are predicted.
