摘要
针对某蓄水期重力坝,利用大型有限元软件ANSYS建立有限元模型,通过分析其结构的变形、应力、应变等因素来研究混凝土重力坝的稳定性、混凝土的开裂情况。模拟结果表明,蓄水期该混凝土重力坝的最大变形在坝顶中心位置;最大拉应力主要分布在坝肩,最大拉应力值出现在接近坝底中心位置,其最大拉应力值为3.53 MPa,小于混凝土的抗拉强度,符合大坝安全标准。模拟结果与实际工程较好吻合,可以为混凝土重力坝设计工作提供借鉴。
For a certain storage period gravity dam, using the large-scale finite element software ANSYS finite element model is established, through the analysis of the deformation of the structure, the stress, strain and other factors to study the stability of concrete gravity dam, concrete crack prop-agation. Simulation results show that the maximum deformation of the concrete gravity dam filling in the center of the crest;maximum tensile stress distribution in the dam abutment, the maximum ten-sile stress values appear in close to the position of the center of the bottom of the dam, the maximum tensile stress values for 3. 53 MPa, less than concrete tensile strength. Meet the dam safety stand-ards. Simulation results and the actual engineering agree well can provide a reference for the design of concrete gravity dam.
