岩体裂隙的网络分析及渗流模型

NETWORK ANALYSIS AND SEEPAGE FLOW MODEL OF FRACTURED ROCKMASS

本文首次运用图理论来阐述裂隙网络的基本构成和特点,并用数值矩阵将复杂裂隙系统的组构关系形象地表示出来,为岩体裂隙的数学描述提供了新方法,由此所导出的裂隙渗流离散数值模型能较好地描述岩体中渗流分布的极不均匀性和渗透空间各向异性机制,为解决工程中的裂隙岩体渗流问题做了新的探索。

Graph theory was applied to describe the basic composition of fracture networks and numerical matrixes were used to express the structures of complex fracture system in image for the first time, which provided a new method for the mathematic description of fractured rockmasses. The discrete numerical model of seepage flow in fracture networks developed on the basis of the above research can fairly well reflect the mechanism of the strong heterogeneity and anisotropy in permeability of fractured rockmasses. The model will be more effective for solving the problems of seepage flow in fractured rockmass in engineering.
