摘要
抗震性能分析是混凝土重力坝设计的重要内容。文章以辽宁丹东凤城市石桥水电站大坝为例,研究了基于ANSYS的重力坝抗震性能分析。结论显示,第一和第三主应力下的最大拉应力和压应力值均未超过大坝的最大抗压和抗拉强度;大坝在水平方向地震力的作用下位移分布情况良好,竖直方向整体拉应力受力面积在7%以下,重力坝设计满足抗震设计要求。
The analysis of seismic performance is an important element in the design of concrete gravity dam. Taking the dam of Shiqiao hydropower station in Fengcheng of Dandong City of Liaoning Province as an example, the paper studies the seismic performance for gravity dam based on ANSYS. The results show that, the maximum tensile stress and the compressive stress under the first and third main stresses are not more than the maximum compressive and tensile strength of the dam, the displacement distribution of the dam is good under the action of horizontal seismic force, the stress area of the vertical overall tensile stress is below 7%, and the design of the gravity dam could meet the requirements of the seismic design.
