冗各水电站复杂岩溶水环境成库条件示踪探测研究

通过三个投剂点的示踪探测,探明了冗各水电站河湾地快复杂岩溶水流场的类型、结构、规模,计算出了岩溶水管道流的流速、流量、容积、串联暗潭多少等流场特征参数,分析判断出了地下分水岭的位置及高程,为该水电站成库条件评价起到了决定性的作用。该实例表明,示踪探测已经走向成熟,对于复杂岩溶水文地质环境的工程勘察,可起到重要作用。

Study on the Tracing and Detecting of Forming Condition of Reservoir in Complex Karst Water Environment for Rongge Hydropower Station

Through the tracing and detecting at three testing spots,the type,structure and size of the complex karst water field are explored for Rongge hydropower station,the feature parameters such as velocity of flow,discharge,cubage and the underground pools in series are calculated for the karst conduit-flow field,and the location and elevation of the underground watershed are estimated which play the key role for the evaluation of reservoir-formed conditions of the power station.The example indicates that the tracing and detecting tend to maturation which has the important function in the investigation of hydrogeological environment for karst water.
