摘　　要：砌石拱坝具有就地取材、施工简便、能充分发挥石材抗压能力等优点,在小型水利工程中得到广泛应用。但砌石拱坝由于体型单薄,在上游水压力的作用下,极易出现应力集中和整体失稳现象。该文依托双江水库工程,采用三维有限元数值模拟方法,对砌石拱坝开展坝体应力分析及整体稳定性研究。研究成果对类似砌石拱坝工程具有参考价值。Masonry arch dam has the advantages of using local materials,simple construction and giving full play to the compressive capacity of stone,so it has been widely used in small-scale water conservancy projects.However,due to the thin shape of masonry arch dam,stress concentration and overall instability are easy to occur under the action of upstream water pressure.Based on the Shuangjiang Reservoir Project,the three-dimensional finite element numerical simulation method is used to study the stress analysis and overall stability of the masonry arch dam.The research results are of reference value to similar masonry arch dam projects.
