摘　　要：王甫洲电站为低水头径流式电站,厂房进水口拦污栅在运行初期即发生了拦污栅条不同程度破坏的事故,影响了电站的安全运行和效益。结合现场原型观测进行了拦污栅振动计算,从提高拦污栅的自由振动频率出发,提出了拦污栅加固方案。The intake screen racks of Wangfuzhou run off river hydropower plant were damaged in different degrees not long after being put to use and couldn＇t operate yet, on the basis of prototype observation data in-situ, the vibration stresses of the screen racks are calculated, and a reinforcing plan for them by enhancing their free vibration frequency is proposed.
