摘　　要：为深入研究水库混凝土面板砂砾石坝坝体应力变形特性,以甘肃省民乐县海潮坝水库工程为例,应用有限元软件构建起水库混凝土面板砂砾坝三维模型,并对竣工后蓄水过程中大坝坝体受力变形、面板变形及连接板和防渗墙间接缝沉降变形展开分析探讨。结果表明,无论水库大坝、混凝土面板,还是连接板和防渗墙间接缝,受力变形及沉降均未超出规范许可范围,水库大坝运行基本处于安全稳定状态。The purpose of this paper is to deeply study the stress and deformation characteristics of the dam body of the reservoir concrete face sand gravel dam.Taking the Haichaoba Reservoir Project in Minle County,Gansu Province as an example,a three-dimensional model of the reservoir concrete face sand gravel dam is built by using finite element sofware.The stress deformation of the dam body,the deformation of the panel and the settlement deformation of the joint between the connecting plate and the cut-off wall during the impoundment process after completion are analyzed and discussed.The results show that no matter the dam,concrete face plate,or the joint between the connecting plate and the cut-off wall,the stress deformation and settlement are within the allowable range of the specification.The dam is basically in safe and stable operation.
