摘要 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。 Given the complexity and difficulty of tracing and detecting the Karst seepage field, the problems such as imperfect information and discrepancies often arise to calculate the underground capacity of karst reservoir using hydrogeological, hydraulic, and hydrological parameters. The capacity calculation based on tracing and detecting method is not dependent on those parameters. The study and calculation on the underground capacity of Lujiaoba depression reservoir indicate that under certain conditions, tracer agent is ergodic to seepage field due to its diffusion rule and is measurable of water filling space in the seepage flow field due to the conservation of mass. For these reasons, information about flow field obtained through tracing and detecting is more completed, and the underground capacity of Karst reservoir calculation is more accurate.
