摘要(Abstract)：

基于真实的岩体剖面图片,通过剪裁、二值化、矢量转化,再导入数值计算软件,建立数值计算模型,进行模型水压力场、渗流速度场分析及渗透系数的计算。分析发现,从水流入口至出口,水压整体呈递减规律;岩石的裂隙中渗流场分布不均匀,渗流活跃的通道主要是左右串通好的裂隙,在不同水流入边界条件下,依据达西定律计算获得的岩体渗透系数存在差异。
Based on real cross-sectional images of rock, by tailoring, binary and vector conversion, then importing numerical calculation software, a numerical model was established, the water pressure field and seepage velocity field were analyzed and the permeability coefficient was calculated. From analysis it was found that the water pressure showed the law of progressive decrease from the water inlet to the outlet; The seepage field was uneven, the active channels of seepage were mainly the well connected cracks, and in different boundary conditions, the permeability coefficient of rock mass calculated based on Darcy's law was different.
