一、关于土坝完建期拦洪标准问题土坝完建期拦洪,标志着大坝基本建成,汛期即可拦洪,甚至部分蓄水,其拦洪标准是关系到土坝渡汛安全的重大问题,必须在施工设计中慎重考虑。决定土坝完建期拦洪标准的因素主要有:(一)水工建筑物等级;(二)拦洪坝高和相应的拦洪库容,以及失事对下游造成危害的严重程度;(三)下游防洪的特殊要求;(四)临时泄洪设施的繁简及非常泄洪条件;(五)设计
First, on the construction of earth dam flood control standards Earth dam construction completed flood control, marking the dam basically completed flood season can flood control, and even part of the water, the flood control standard is related to the earth dam flood safety The major issues must be carefully considered in the design of the construction. The main factors that determine the standard of flood control for earth dam construction are: (1) the level of hydraulic structures; (2) the height of the dam and the corresponding flood storage capacity, and the severity of the damage caused by the accident to the downstream; (3) (1) The special requirements for flood control in the downstream; (4) The simplification and very flood discharging conditions of temporary flood discharge facilities;
