摘要
截流工程是水电站工程建设施工的关键工程,截流时水力条件及边界条件复杂,各项条件指标变化较大,在施工中根据工程截流模型试验水位、流速测点布置,对截流期间进行原型观测,测定的水文信息对截流施工与指挥调度有着重要的指导意义。文章简述了湖北省碾盘山水利水电枢纽工程截流水文勘测内容和手段,对勘测成果进行了分析,截流水文要素监测成果基本反映了截流期各水力要素的变化特征和规律,为汉江流域的其他工程的截流积累了宝贵的经验和理论参考依据。
The river closure engineering is the key to the construction of hydropower station construction engineering.The hydraulic condition and boundary conditions are complicated during river closure.The condition index change is bigger.The prototype observation is implemented during closure during construction according to the test water level and flow velocity measuring point layout of the engineering closure model.The measured hydrological information has important guidance significance for river closure construction and regulation.The closure hydrological survey content and methods of Hubei Nianpanshan Water Control Project are briefly discussed in the paper.The survey results are analyzed.The closure hydrological element monitoring results reflect change characteristics and regularity of hydraulic elements during river closure mainly,thereby accumulating valuable experience and theoretical reference basis for other projects of Hanjiang River Basin.
