摘　　要：桃源水电站是修建在滨湖冲积平原流域尾阈的低水头大流量河床径流式电站,其额定水头5.6m,尾水流速为1~3m/s,通过近年来水下检查发现尾水渠基础和河床出现较大冲刷破坏,导致尾水持续降低,对机组安全造成较大影响。文章借鉴类似工程经验,研究经济、安全的工程措施,按分步实施的原则恢复尾水渠设计体型,确保建筑物安全。Taoyuan Hydropower Station is a low-head,high-flow,run-of-river power station built on the alluvial plain at the tail-end of a lake basin.It has a rated head of 5.6 meters,and the tailwater velocity ranges from 1 to 3 m/s.Recent underwater inspections revealed significant scouring damage to the foundation of the tailrace channel and riverbed,resulting in a continuous decrease in tailwater level,which significantly impacts the safety of the turbine units.This paper draws on the experience of similar projects to research economical and safe engineering measures.It proposes a step-by-step implementation approach to restore the designed shape of the tailrace channel and ensure the safety of the structure.
