摘　　要：驮英水库坝址区岩体褶皱构造发育,岩层扭曲严重,层间软弱夹层发育,对坝型选择影响大。设计坝型为沥青混凝土心墙堆石坝,软岩开挖料能否作为堆石坝填筑料是需要重点研究的工程地质问题。论述了对坝址区岩体褶皱构造、软弱夹层和软岩筑坝这3个工程地质问题的勘察研究成果,解决了影响驮英水库大坝建设的重要工程地质问题。The rock mass in dam area of Tuoying Reservoir is characterized by developed fold structure,seriously distorted rock strata and developed weak interlayer,which renders significant influence on the selection of dam type.Since asphalt concrete core rockfill dam was designed,whether the soft rock out of excavation is able be used as the filling material of rockfill dam become the key engineering geological issue.The author demonstrated the investigation results of three important geological issues of fold structure,weak interlayer and soft rock damming for the main dam construction of Tuoying Reservoir Project.
