由于喀斯特渗流场勘察测试的困难性,利用喀斯特水文地质及水力学、水文学参数计算喀斯特水库地下库容时,存在信息不全、误差大等问题,而利用示踪探测方法计算喀斯特水库地下库容时,回避了计算中对喀斯特水文、水文地质等参数的依赖。通过鹿角坝洼地水库地下库容的研究计算表明,在一定条件下,示踪剂因扩散规律而对渗流场具有遍历性、因质量守恒而对流场充水空间具有可测性,因而示踪探测获得的流场信息更全面,计算的喀斯特水库地下库容更接近实际。
Due to the difficulty of the investigation and test of karst seepage field, there are some problems such as incomplete information and large error when using karst hydrogeology and hydraulics and hydrology parameters to calculate the underground storage capacity of karst reservoirs. However, when calculating the underground storage capacity of karst reservoirs by using the tracing detection method, Avoid the calculation of karst hydrology, hydrogeology and other parameters of dependence. The research on the underground storage capacity of the reservoir shows that under certain conditions, the tracer has ergodicity to the seepage field due to the diffusion law. Because of the mass conservation, the space for water flow in the flow field is measurable, The obtained flow field information is more comprehensive, and the calculated underground storage capacity of karst reservoir is more realistic.
