摘　　要：铜灌口水库工程建设中,为了减少坝基开挖,降低施工强度,节省工程投资,并保护工程区环境,通过对坝基覆盖层进行勘探、试验,结合坝体结构设计,采用三维有限单元法,研究了河床覆盖层不同的开挖方案时坝体、面板和接缝系统的应力变形特性,最终确定了坝基覆盖层合理利用的设计方案。Based on dam structure design, stress deformation features of dam, panel and joint system of excavation programs for different riverbed covering layers are studied through exploring and testing dam foundation covering layer, and adopting three-dimensional finite element method in Tongguankou reservoir project construction in order to reduce dam foundation excavation, decrease construction intensity, save project investment, and protect environment of project area. Design program of rationally utilizing dam foundation covering layer is finally determined.
