The solution indicates that the vadose water of the measuring weir behind xiao shan hydropower station dam mainly comes from basalt and the unconformity of basalt and asdesite . The solution provides the disposal of the dam with a lot of fixed-amount basis.Key words Vaduse field, Inversion, Leakage1 前言 小山水电站位于吉林省抚松县松江河上游段，距小山火车站 5~6km，系松江河梯级电站的第一级。小山水电站为混合式开发工程，引水隧洞 1000 多米长，单引水隧洞自然落差为 17m。小山水电...
