摘　　要：在国家着力改善生态环境的背景下,全国涌现出大批污水处理提标改造工程。本文采用有限元整体建模的方法,对浙江钱塘江边某污水厂后物化池加高改造进行了分析,发现采用增加水平拉梁,将池壁顶部自由端转化为简支端,能大幅降低池壁及底板弯矩,为构筑物水池加高改造设计提供了理论依据,且指导了工程实践。A large number of sewage treatment renovation project emerged ,while national efforts are made to improve the ecological environment. In this paper, a finite element modeling of a heightened sedimentation tank of a wastewater treatment plant, located along Qiantang River, was carried out and analyzed. It was found that the installing of level pull beam, which converts the the free ends of the top of the tank wall into simply supported ends, can significantly reduce wall and bottom slab moments, and this provided a theoretical basis for the design of the heightening of reinforced concrete tanks and engineering practice guidance.
