渗流问题是边坡稳定性分析的重点、难点之一。该文以有限差分法求解渗流问题的原理为基础,基于山西省阳泉市307国道复线路堑边坡的边界条件和地质模型,运用有限差分软件深入分析了侧向和垂向双向补给条件下坡体中渗流场的特征,所得浸润曲线几何特征与实际情况十分吻合,为边坡稳定性评价提供了详实的水文地质资料。
Seepage problem is one of the key and difficult points in slope stability analysis. Based on the principle of finite difference method to solve the seepage problem, based on the boundary conditions and geological model of the cutting slope of 307 national highway in Yangquan city, Shanxi Province, finite element software was used to analyze the influence of lateral and vertical bi- The characteristics of the seepage field and the geometrical characteristics of the infiltration curve are in good agreement with the actual situation, providing detailed hydrogeological data for the slope stability assessment.
