裂隙网络介质地下水流运动参数反演分析

Inverse Analysis of Parameters for Groundwater Flow Movement in Fractured Network Media

根据锦屏水电站坝址区揭示的地质、水文地质情况,基于Monte-Carlo法,建立了三维随机裂隙网络模型。基于结构面控制反演法原理,并以水文地质条件为基础,以水位拟合为目标,结合所建立的数学模型和最优化方法,反演裂隙网络介质的几何参数和渗透参数。参数反演结果表明了所建模型的合理性,该模型能够应用于工程实际。

According to the geological and hydrogeological conditions exposed in the dam region of Jinping Hydroplant, the physical and mathematical model for the groundwater movement through the 3D fractured network media of rock mass is established in this thesis on the basis of Monte-Carlo method. Based on discontinuity-control inverse theory, combined mathematical model with optimization method, some relative parameters of fractured network media are inversed with calibration of water table as the objective function. The parameter results show that fractured network media model is reasonable and can be applied in engineering practice .
