摘要
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 saturated and unsaturated seepage theory,a numerical simulation on the seepage field in an anisotropic complex geological body was done.A mine which had a typical fold shape geological structure in Fuxin was taken as research background,a three-dimensional geological model was built using the Kriging interpolation method,and then the pressure gradient changes in the geological body were simulated and analyzed,when the principal direction of hydraulic conductivity and global coordinate system were of different angles.The results showed that the pressure gradient reached the maximum at 90°.The type of geological structure and formation were the key factors of the direction and density of the pressure gradient.
