通过对天生桥一级水电站引水系统非均质各向异性岩体渗流场的模拟计算，提出了三维非均质岩体各向异性渗流场的计算方法，并导出三维排水廊道边界的计算公式和三维自由水面边界的迭代方法．通过对不同参数对渗流场影响的研究和各种运行工况三维渗流场特征的分析，得出了三维各向异性渗流场的一些基本规律，为高压引水管道的设计、施工提供了合理的设计依据．
Based on the simulation calculation of the seepage field in the inhomogeneous anisotropic rock mass of the Tianshengqiao-1 hydropower station, the anisotropic seepage flow field of the three-dimensional heterogeneous rock mass is calculated and the calculation formula of the three-dimensional drainage corridor boundary is derived Iteration Method of Three - dimensional Free Water Surface Boundary. Through the study of the influence of different parameters on the seepage field and the analysis of the characteristics of the three-dimensional seepage field under various operating conditions, some basic laws of the three-dimensional anisotropic seepage field are obtained, which provides a reasonable design for the design and construction of the high-pressure water diversion pipeline in accordance with.
