Finite Element Analysis and Optimal Design of Prefabricated Assembled Water Retaining Weir Plate

地势起伏较大的海绵城市项目建设,需在生物滞留带中设置挡水堰板,同时实现径流总量、径流峰值和径流污染控制等多重目标。结合工程实际,对优化前后的挡水堰板结构进行三维有限元建模计算和分析,提出相对合理的尺寸建议范围,为类似工程提供计算思路和借鉴。

The sponge city project construction with the larger undulating terrain is required to set up the water retaining weir plate in the biological retention zone. At the same time, the multiple targets of runoff volume, runoff peak value and runoff pollution control are realized. Combined with the engineering practice, this paper carries out the 3D finite element modeling calculation and analysis of the water retaining weir plate structure before and after optimization, and puts forward the relevantly reasonable proposal range of dimensions, which can be referred for the design of the similar projects.
