浙江皎口水利枢纽包括大坝、溢洪道、泄洪(放空)底孔、电厂等建筑物。底孔建成后使用频繁,到七六年底前已启闭400余次。运行水位67.17～50.00米,开度0.01～2.5米。运行中存在以下主要问题: 泄流过程中均产生不同程度的振动。相对开度在0.07及0.95附近时振动强烈,伴随 Zhejiang Jiao Kou water conservancy hub including dams, spillway, flood discharge (vent) bottom hole, power plants and other buildings. After the bottom hole is built and used frequently, it has opened and closed more than 400 times before the end of the seventy-six. Operating water level 67.17 ~ 50.00 meters, the opening of 0.01 to 2.5 meters. The following major problems in operation: the discharge process have different levels of vibration. When the relative opening is around 0.07 and 0.95, the vibration is strong and accompanied
