摘要
针对旺隆水库泥岩心墙防渗料进行一系列的室内土工试验和现场碾压试验,研究了泥岩心墙防渗料的颗粒级配、击实、渗透性及现场碾压等特性,提出泥岩心墙防渗料的合理级配范围和压实控制干密度,级配范围内的泥岩防渗料具有良好的抗渗性能和力学性能。采用风化泥岩作为土石坝心墙防渗料是成功的,对同类工程中心墙防渗料的设计施工有借鉴和参考作用。
A series of laboratory soil tests and field rolling tests are carried out for the impervious material of mudstone core wall in Wanglong reservoir.The characteristics of grain gradation,compaction,permeability and field rolling of the impervious material for mudstone core wall are studied.The reasonable gradation range and compaction control dry density of the impervious material for mudstone core wall are proposed.The mudstone impervious material within the grading range has good impermeability and mechanical properties.It is successful to use weathered mudstone as impervious material for core wall of earth-rockfill dam,which can be used for reference in design and construction of similar projects.
