摘　　要：西南地区某水库坝址具备修建重力坝的地形地质条件,但坝区工程地质复杂,处理范围内主要的地质缺陷有泥化夹层、软弱岩体、破碎带等,这些地质缺陷对重力坝的体形选择和抗滑稳定等,均会产生较大影响,需要通过相应的基础处理及结构措施,使地基能适应重力坝所要求的边界约束条件。A reservoir dam site in the southwest China has the topographical and geological conditions for the construction of gravity dam,but the engineering geology of the dam area is complicated.The main geological defects in the treatment range are argillated interlayer,weak rock mass,fracture zone and so on.These geological defects have a great influence on the shape selection and anti-sliding stability of gravitydam.Through the corresponding foundation treatment and structural measures,the foundation can adapt to the boundary constraints required by gravity dam.

关 键 词：深层抗滑稳定 重力坝 软弱夹层
