| 摘 要： | 裂隙化岩体广泛存在于地表浅层,为主要的地下水渗透介质之一,而裂隙网络构成地下水及溶质在裂隙化岩体中运移的主要甚至唯一导水通道.根据图论知识将裂隙网络概化为非连通图,采用图这种数据结构表示三维裂隙网络数据.编写了计算机程序识别裂隙化岩体中沿水力梯度方向的渗流路径,剔除对渗流无贡献的裂隙,可明显缩短裂隙网络地下水渗流与溶质运移数值模拟计算时间,使大尺度裂隙网络渗流与溶质运移模拟研究与工程应用的可行性显著提高.

| Abstract: | The fractured rock, one of the major types of seepage media for groundwater flow, exists widely in the shallow layers of the earth. It is commonly realized that fracture networks in fractured rocks constitute the main or the unique flow path for groundwater flow and solute transport. Based on the graph theory, the fracture network transporting groundwater was conceptualized as the unconnected graph, in which the algorithms of data structures were applied to storing and organizing the data of the stochastically distributed fractures. A computer program was developed to identify the flow paths along the groundwater flow gradient in fractured rocks and remove the disconnected fractures from the network. Consequently, computation efficiency can be then significantly increased for the identification and numerical simulations of groundwater flow and solute transport become more practicable at a large field scale. |
