摘　　要：由于料源变化,狮泉河水电站工程大坝防渗料只能采用距坝址约50 km的塔那波料场黏土料,塔那波料场黏土料属于分散性黏土,从抗渗透变形能力考虑,需对其进行改性。经过论证和经济比较,决定采用黏土与砂石料按质量比50%:50%的比例掺和,掺和料作为心墙料使用。Due to the change of material source, the material for the dam seepage control of Shiquanhe Hydropower Station adopted the clay soil of Tanabo site, 50km away from the clam site. Because such clay soil is dispersive clay, it should be modified to meet the need of infiltration and anti-deformation capability. Based on demonstration and comparison, it is decided to adopt the admixture ratio of clay to sand-rock material of 50%：50% and then the mixture material is used as core wall material of the dam.
