摘　　要：旺隆水库大坝为泥岩心墙土石坝。工程区分布地层主要为侏罗系中统沙溪庙上亚组砂质泥岩、泥质粉砂岩间夹砂岩,属典型的红色地层。防渗材料较为匮乏,防渗料成为控制该工程投资及进度的关键因素。通过对坝址区砂质泥岩的系列试验工作,结合试验指标并经三维有限元分析计算,结果表明:大坝心墙防渗料采用风化泥岩料填筑,上、下游坝壳采用泥岩、砂岩、粉砂岩等土石混合料填筑是可行的,结构设计和填筑标准合理。The dam of Wanglong Reservoir is an earth-rockfill dam with mudstone central core.The strata in the project area are mainly sandy mudstone and argillaceous siltstone interbedded sandstone of the upper subgroup of Shaximiao Formation in the middle Jurassic system,which is a typical red stratum.The impervious material is scarce,and the impervious material has become a key factor to control the investment and progress of the project.Through a series of tests on sandy mudstone in the dam site,combined with the test indexes and through three-dimensional finite element analysis and calculation,it is concluded that it is feasible to fill the impervious material of the dam core wall with weathered mudstone,and to fill the upper and lower dam shells with mudstone,sandstone,siltstone and other soil-rock mixtures.The structural design and filling standards are reasonable.
