L型城市应急防洪屏是一种新型防汛应急抢险装备,论文采用理论分析和有限元计算结合的方法,对防洪屏挡水过程中的受力稳定条件和应力应变特性进行了研究,可为L型城市应急防洪屏的设计提供参考依据。结果表明,防洪屏在挡水过程中,其体型尺寸需满足相应的长高比条件,在静、动水作用下,防洪屏的最大应力和应变发生在防洪屏踵部边缘两侧,最大变形发生在顶部两侧。
- Abstract:
-
L-shaped urban emergency flood barrier is a new flood emergency equipment which can be used in urban flood control. In this paper, the stability conditions and stress-strain characteristics of flood barrier are studied with theoretical analysis and finite element calculation, which can provide references for the design of L-shaped urban emergency flood barrier. The results show that the size of flood barrier should meet the corresponding aspect ratio in order to keep stable in operation. Under the action of static and dynamic water flow, the maximum stress and strain of flood barrier appear on both sides of heel, and the maximum deformation always occur on the two sides of top.
