现浇圆形涵管在灰场排洪系统中常用,但关于其设计计算过程的资料很少。为解决工程实际需要,本文使用STAAD软件建模进行有限元求解将应力转化为内力弯矩,并将结果和弹性中心法结果比较,两者结果基本一致,表明对平面应变问题,应力法求解符合工程需要。 Cast-in-place circular culverts are commonly used in ash discharge systems, but there is little information about their design and calculation process. In order to solve the practical needs of the project, this paper uses STAAD software modeling to solve the finite element method, and converts the stress into moment of internal force, and compares the result with the result of elastic center method. The results of the two methods are basically the same, which shows that the solution of plane strain problem and stress method accord with Engineering needs.
