摘　　要：根据DXS水库面板坝基础工程地质条件,对平趾板与斜趾板两种布置形式进行比较,为减少开挖量,降低上游的高边坡,采用斜趾板与延长防渗板的布置型式。并结合工程实际简要介绍了该面板坝趾板设计要点。工程投运3年多,面板坝趾板混凝土质量良好,趾板无裂缝,水库无渗漏,大坝运行正常。For the concrete face-slab dam of DXS Reservoir, two alternatives of flat toe slab and oblique slab were compared combined with the foundation engineering geological conditions, and the oblique toe slab alternative with extended anti-seepage slab was adopted due to less excavation quantity and lower upstream bank slope. A brief in-troduction was made on the key points of toe slab design combined with the actual conditions of the project. The project has been operating normally for more than 3 years, showing good concrete quality, without crack at toe slab or reservoir seepage.
