【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。更多还原

【Abstract】 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 gravel 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.更多还原
