某拱坝持久工况下坝体应力变形特性计算分析
|
摘要
为研究某拱坝在规范给出的持久工况下坝体应力变形规律特点,利用ANSYS软件建立坝与地基相互作用的三维有限元模型,对拱坝在持久工况规定荷载作用下坝体应力变形规律进行了分析,结果表明坝体的应力变形分布符合一般规律,位移及应力峰值均小于规范规定值,该拱坝设计方案合理,安全可靠。
In order to study a dam stress deformation law characteristics under persistent condition within the given specification,a three-dimensional finite element model of the interaction between the dam and the foundation with ANSYS software was built,the provisions under load conditions lasting arch dam in deformation of the stress were analyzed;The results showed that the deformation of the dam stress distribution in line with the general law,the displacement and stress peak value is less than specification,the arch design is reasonable,safe and reliable.
