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。 Through the tracing detection of three dosing spots, the type, structure and scale of fast and complex karst water flow in the river bay of the various hydropower stations were ascertained, and the flow velocity, flow rate and volume of the karst water pipeline were calculated. How many other flow field characteristic parameters, analyzed and judged the position and elevation of the underground watershed, played a decisive role for the evaluation of the reservoir conditions for the hydropower station. This example shows that tracing detection has matured and can play an important role in engineering investigation of complex karst hydrogeological environments.
