【摘要】 水电站复杂的地形条件、水文地质条件往往造成岩体渗透特性在空间具有明显分区、分带特征和各向异性。基于大岗山水电站厂坝区工程地质和水文地质条件,建立各向异性渗流场的三维反演分析模型,选择水头作为反演变量,利用钻孔抽注水试验,反演得到厂坝区的三维天然渗流场,计算结果表明：厂坝区的反演渗流场与工程实际基本一致,所得到天然渗流场可作为厂坝区施工期和运行期渗流分析以及渗控措施优化的依据。更多还原

【Abstract】 Complex geological and hydrological condition commonly result in zoning and anisotropic permeability. According to the engineering geology and the hydrogeology of Dagangshan hydropewer station,a 3D back analysis model is established for anisotropic seepage field and water head is selected as variables of back analysis;combing with experimental results of drilling test,3D nature seepage field of station and dam region is obtained and compu- tational solution shows that the seepage field obtained by back analysis is basically is in agreement with actual pro- jeer and can be as reference of optimizing seepage measures.更多还原
