摘要
为了研究高椅大坝的安全性,利用大坝运行期间历年的监测资料,应用ANSYS有限元仿真分析,对高椅大坝进行安全复核。通过对其结构应力及变形的分析来研究混凝土重力坝的稳定性。大坝的安全复核结果表明,在设计运行工况下该坝的最大变形在坝顶中心位置,最大拉应力出现在坝踵处,其最大拉应力值为1.14MPa,小于混凝土的抗拉强度,符合大坝的安全标准。分析表明,仿真分析的结果与大坝历年运行的监测值吻合较好,大坝是安全的。
In order to research the safety of Gaoyi dam,this paper applies ANSYS finite element simulation analysis to check the safety of gaoyi dam by using the monitoring data of past years during the dam operation.The stability of concrete gravity dam is studied by analyzing its structural stress and deformation.The safety re-check results of the dam show that the maximum deformation of the dam is at the center of the dam crest,and the maximum tensile stress occurs at the heel.The maximum tensile stress value is 1.14 MPa,less than the tensile strength of concrete and meets the safety standard of the dam.The conclusion shows that the simulation results are in good agreement with the monitoring data of the dam,and the dam is safe.
