水闸消能防冲优化设计

Optimization Design of Sluice on Energy Dissipation and Anti-scour

以具体水闸工程为例,进行了消能方式选择及水闸消能防冲设计原则的探讨,并基于此提出水闸泄水不分区(方案一)及水闸分三区泄水(方案二)的分区消能设计方案,从开挖、混凝土及钢筋工程量,消力池深、消力池底板厚、消力池水平段长及总投资等角度进行该水闸两种消能防冲方案的比较,最终确定选用水闸分三区泄水的方案,且运行效果良好。

Take a concrete sluice project as an example,the selection of energy dissipation mode and the design principle of energy dissipation and anti-scour for sluice are discussed in this paper.Based on this,a scheme(Scheme 1)of sluice discharge without zoning and a scheme(Scheme 2)of sluice discharge into three zones are proposed..Two schemes of energy dissipation and anti-scour of sluice are compared in terms of excavation,quantity of concrete and reinforcement works,depth,bottom plate thickness and horizontal section length of stilling basin and total investment.Finally,Scheme 2 is determined and is in good operation condition.
