摘　　要：消能设计是沿海挡潮闸设计中重要的一部分,规范中对挡潮闸消能设计的工况和水位组合尚未有明确的规定。以广州市增城区仙村水闸为例,根据挡潮闸的特性,选取3种工况,确定了4种水位组合,进行水闸消能计算。演算结果得出水闸控制运行判定条件,确定水闸开度和消力池尺寸,希望对同类工程的消能设计提供参考。Energy dissipation design is an important part of coastal tidal sluice design.However,there are no clear regulations on the working conditions and water level combination of tidal sluice energy dissipation design in the code.Taking Xiancun sluice in Zengcheng District,Guangzhou as an example.According to the characteristics of tidal sluices,three working conditions and four water level combinations are selected to calculate the energy dissipation of the sluice according to the characteristics of tidal sluice.The calculation results put forward the judgment conditions of sluice control operation,determine the sluice opening and the size of the sink.It is hoped to provide reference for the energy dissipation design of similar projects.
