摘　　要：心墙堆石坝防渗材料类型较多,有粘土、土工膜、沥青混凝土等,碎(砾)石土应用较少。结合西南某工程,在天然土料贫乏的情况下,对发育在侏罗系地层中的滑坡堆积物———含块石、碎(砾)石土进行了研究,其各项技术指标均满足心墙防渗土料的质量要求,且储量丰富。There are many sorts of impervious materials （ such as clay, geomembrane and asphalt concrete, etc. ） applied for building rockfill dams with core, however, broken gravel soil is less used. A study was performed on the landslide deposit （covering block stones, broken gavel soil） developed in the stratum of Jurassic System in the condition of indigent natural material for a certain project. The technical indexes satisfy quality requirements of impervious core material that has abundant reserves,
