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。
In the research work, positive analysis, inverse analysis and in situ observation data analysis adopt the same deterministic model. The “equivalent deformation parameters” of the rock foundation were inversely analyzed by means of three-dimensional finite element method and probability statistics. Evaluated the safety of the project operation status and predicted the displacement and safety of the unimportant event.
