摘　　要：注水式城市应急防洪箱是一种高分子材质的防汛应急抢险新装备,采用理论分析和有限元计算结合的方法,对防洪箱挡水过程中的受力稳定条件以及箱体的应力、应变特性进行分析,结果表明:由防洪箱在挡水过程中的受力特性可知,在同一注水条件的不同挡水高度下,防洪箱的最大应力和变形均发生在迎水面,其中最大应力在迎水面底部,最大变形发生在迎水面中部。The water-filling flood control box is a new equipment of polymer material for flood control and emergency rescue.In this paper,the force stability conditions and the stress-strain characteristics of the flood control box are studied by theoretical analysis and finite element calculation.The results show that the maximum stress and deformation of the flood control box occur at the upstream face under the same water filling condition with different retaining heights.The maximum stress is at the bottom of the upstream face and the maximum deformation is at the middle of the upstream face.
