| 摘 要： | 本文在充分研究了三峡工程坝址区岩体所处的地质、水文地质环境基础上，以流场中若干点水头实测值与计算值之误差为目标函数，考虑到岩体裂隙结构面在控制岩体渗流中的作用，用三维有限单元法与最优化方法相结合，反求岩体的水文地质参数。

| Abstract: | On the basis of a thorough study of geological hydrogeological environment over the rock mass at the dam site area of Three Gorge project, taking the error between the measured value and the calculated value of the water head of a certain amounts of points in the flow field as object functions, considering the controlling action of the fissure structural plane of rock mass in the rock mass seepage, this paper makes back analysis of the hydrogeological parameters of rock mass by using the three dimensional FEM combined with the optimization method. |
