基于Petrel软件实现的三维地质模型,提出了一种考虑整体滑动的三维极限平衡新方法。假设各块段重心点作用在一条直线上且与主滑方向一致,利用三维地质模型得到的滑动面表面积、滑体体积以及重心点处滑面切线角度,在忽略块段间竖向切力的情况下,建立了土质边坡力的多边形闭合和极限平衡条件的稳定性分析方法。通过经典算例的验证,该方法计算简单,具有很好的可行性和实用性。
Based on the 3D geological model implemented by Petrel software, a new three-dimensional limit equilibrium method considering global sliding is proposed. It is assumed that the center of gravity of each block acts on a straight line and is consistent with the main slip direction. By using the surface area of the sliding surface, the volume of the sliding body and the tangent angle of the sliding surface at the center of gravity, the vertical shear force In the case, the method of stability analysis of polygonal closure and limit equilibrium conditions of soil slope force is established. Through the verification of the classical example, this method is simple and has a good feasibility and practicability.
