基于饱和非饱和渗流理论,针对各向异性复杂地质体内渗流场问题进行模拟分析。以阜新某矿典型的褶曲状地质结构为研究背景,应用克立格插值法对地质模型进行三维构建,并在此模型的基础上模拟分析了渗透系数主方向与整体坐标系成不同角度时,压力梯度在地质体内的变化情况。研究结果表明在90°时压力梯度最大,地质体的结构及地层的走向是决定渗流场内压力梯度等值线的走向和疏密程度的关键因素。
Based on the theory of saturated unsaturated seepage, the seepage field in anisotropic complex geology is simulated. Taking the typical fold-shaped geological structure of a mine in Fuxin as the research background, a three-dimensional geological model is constructed by using Kriging interpolation method. Based on this model, when the main direction of permeability coefficient is different from the global coordinate system, Pressure gradient in geological body changes. The results show that the pressure gradient is the largest at 90 °. The structure of the geological body and the direction of the formation are the key factors that determine the direction and density of the pressure gradient contour in the seepage field.
