摘要
根据单裂隙饱和-非饱和渗流实验结果，确立了裂隙岩体渗流时饱和度与负压及饱和-非饱和渗透系数与负压之间的实验关系式，进而建立了有暴雨入渗下三维裂隙网络饱和-非饱和渗流数学模型，针对龙滩水电站左岸蠕变体边坡进行了不同工况下的渗流与稳定性分析，并相应给出了其高边坡工程安全施工建议措施．
According to the experiment studies of saturated-unsaturated flow in a single fracture, the ex-periment relatlonships of saturation to pressure head and saturated-unsaturated hydraulic conductivity to pres-sure head of fractured rock masses are established' Subsequently, the saturated-unsaturated seepage flow mod-el of 3-dimensional fractured network under rainfall is built. Seepage analysis and stability analysis under dif-ferent working conditions is made for the left high slope of Lotan hydropower station. Correspondingly, somesuggestions of construction safely of the high slope are given.
