摘　　要：虹吸井是电厂冷却水系统中的重要水工建筑物,堰顶高程和断面面积是影响其自身功能的主要结构参数。本设计基于某电厂工程资料,结合水力特性物理模型试验确定虹吸井的结构参数,从经济性、环保性、安全性3方面对各设计参数进行优化设计。项目自实施以来,运行平稳,年运行费用可节约达510.3万元。Siphon well is an important hydraulic structure in cooling water system of a power plant,which is affected by the crest elevation and sectional area. In this paper, the structural parameters of siphon wells are determined by a certain power plant engineering data, considering the physical model test of hydraulic characteristics. Moreover, the design parameters are optimized from the aspects of economy, environmental protection and safety. The operation has been stable and the annual operation cost can be saved up to ￥5.103 million since implementation of the project.
