摘要 工程岩体的渗透特性研究是其渗流分析和稳定性设计的技术关键·作者以现场岩体渗透结构面概率模型统计资料为依据,采用离散介质方法建立典型裂隙网络模型,提出计算岩体结构面网络的等效渗透系数张量方法·应用等效连续介质模型分析方法研究区域岩体的渗流问题·针对现场的矿山边坡水文地质实体,运用该技术建立了反映岩体渗透各向异性的等效连续介质模型·实例分析表明,该技术途径不但适合工程岩体宏观渗流分析的特点,而且能够较为深刻地认识裂隙渗流的本质· Study on permeation characteristics of engineering rock mass is a key technique to the analysis of seepage flow and stability design. Based on actual statistics used in the probability model for the typical structural plane of rock mass, a typical fracture network model is set up by discrete medium method, and a way to calculate the equivalent permeability coefficient tensor of the structural plane network of rock mass is put forward. An equivalent continuous medium model to reflect the anisotropy of seepage flow of rock mass is used to analyze the seepage flow problems of rock mass in areas of interest, which is set up specially for hydrogeological objects with sloping edges in minefields. As shown by examples, the technique is available to not only make a macroscopic seepage flow analysis in engineering rock mass, but indicate in depth the essence of seepage flow from fissures.
