摘　　要：采用有限单元法,对石河水库浆砌石重力坝坝体输水洞、发电洞目前的工作应力状态进行三维有限元分析,了解洞室沿洞轴线方向应力分布情况,从中找出洞室应力危险部位,为坝体输水洞、发电洞的加固提供了依据.The stress status of the water hole and generating holes of a masonry gravity dam of Shihe reservoir were analyzed by the finite element method.By analyzing the stress distribution along the cavity axis direction of the hole,the stress dangerous parts of the chamber was identified,and these provide a basis for the reinforcement of dam water holes and generating hole.
