| 摘 要： | 采用三维有限差分FLAC3D程序，以二滩工程地下洞群的结构形式为背景，考虑与不考虑节理岩体静水渗流对围岩稳定性进行了大量计算工况的准三维数值模拟。对毛洞开挖时主厂房边墙关键点的位移和主厂房的塑性区进行了系统分析，得到相应的结论，可供大型地下洞室群稳定分析时作为参考。

| Abstract: | The authors use FLAC3D to carry out simulation analysis in underground power house of Ertan Project. FLAC3D is a three dimensional explicit finite-difference program. The authors consider the seepage factor which influence the stability of wall rocks and do lots of numerical simulation analysis with approximate three dimension. Systematical analysis of displacements of key points of side wall and systematical analysis of the plastic zone of the main cavern are carried out. The authors draw some disciplinarian conclusions from the systematical analysis. These conclusions will provide some useful reference for the study of large-scale underground cavern groups. |
