摘　　要：根据大岗山拱坝实际浇筑过程,采用三维有厚度薄层单元模拟坝体的横缝,利用三维非线性有限元计算大岗山横缝开度.仿真中考虑了坝体材料的热力学性能、浇筑过程、环境温度变化、封拱和蓄水过程.仿真结果对大岗山拱坝的接缝灌浆有重要的参考价值.According to the actual concreting process of Dagangshan arch dam,simulating transverse joints of dam by 3Dthin-layer thickness element,this paper adopts 3Dnonlinear finite element to calculate the transverse joints aperture for Dagangshan arch dam.In the simulation,thermal and mechanical properties,concrete construction,temperature variation of environment,crown filling and water impoundment orders are considered.The simulation results are valuable for contact grouting of Dagangshan arch dam.
