摘　　要：落水孔水库大坝为兴建在软岩上的浆砌石双曲拱坝,其坝体压应力大于坝基承载力。本文描述了该坝体通过设置垫层混凝土后的应力复核成果,发现坝基应力改善明显。Luoshuikong Reservoir is a slurry masonry hyperbolic arch dam which is constructed on soft rock.The dam compressive stress is larger than dam foundation bearing capacity.In the paper,stress composite results after cushion concrete being set in the dam are described and it is discovered that dam foundation stress is improved obviously.

关 键 词：拱坝 应力 承载力 垫层混凝土
