裂隙岩体渗流的优势水力路径

优势水力路径是裂隙岩体中的主要渗透通道，是岩土工程中必须考虑和解决的问题。通过分析裂隙岩体渗流优势水力路径的形成机理及编制相应的分析程序，研究优势水力路径的主要表现形式及其应力相关性。研究表明，裂隙岩体中的优势水力路径客观存在于由连通裂隙簇、优势节理裂隙组、主干裂隙等形成的水力连通裂隙网络中，其分布与优势裂隙组和长大裂隙的分布及应力环境极其相关。通过分析裂隙岩体的优势水力路径，确定裂隙岩体中地下水的潜在渗透通道和分布状态，为边坡工程、地下工程等岩土工程的设计施工提供参考依据。

Preferential Flow Pathways in Fractured Rock Mass

Preferential flow pathways are water flow channeling in fractured rock masses, which is the main hydraulic property and must be considered adequately in design in practical engineering. Based on the formation mechanism of preferential flow pathways in fractured rock masses and useful programs, hydraulic properties of preferential flow pathway were briefly discussed and its stress-dependent properties were studied. The results indicate that the preferential flow pathways widely exist in interconnected fracture networks, dominant sets of joints or fractures and faults zone in fractured rock masses. Preferential flow pathways are remarkably correlative with the distribution of dominant sets of fractures and faults zone. According to the results, the water flow channeling and their distribution can be determined. Also, the rational recommendations are made for the design and construction in slope engineering and underground engineering.
