由于岩溶含水系统的高度非均质和各向异性,很难用地下水动力学方法描述岩溶含水系统的水动力特征。为此从理论、试验和数值模拟三个方面总结了岩溶含水系统水动力学的研究成果,指出目前研究岩溶含水系统流态转化的水动力特征参数(临界水利坡度、临界雷诺数)等尚不深入,并提出今后的主要研究方向是通过物理模型和数值模拟等手段来探求裂隙—管道地下水动力学及岩溶含水系统流态转化的水动力特征参数问题,为深入分析岩溶含水系统水动力特征提供了参考依据。
Due to the high degree of heterogeneity and anisotropy of karst aquifer systems, it is difficult to describe the hydrodynamic characteristics of karst aquifer systems using groundwater hydrodynamics. This paper summarizes the research results of the hydrodynamics of karst aquifer system from the aspects of theory, experiment and numerical simulation. It is pointed out that the current hydrodynamic characteristic parameters (critical gradient, critical Reynolds number) Depth and put forward the main research direction in the future is to explore the hydrodynamic characteristic parameters of the fissure-pipeline groundwater hydrodynamics and the karst aquifer system fluid transformation by means of physical model and numerical simulation, etc. In order to further analyze the hydrodynamic characteristics of karst aquifer system The reference basis.
