摘　　要：Midas/GTS岩土数值模拟软件具有简洁的界面、前后处理功能强大的岩土材料模型库,能满足大部分岩土体的破坏模式。建立工程边坡的三维数值模型,并对其计算分析,结果接近真实情况,且计算结果相对安全。本文采用该软件与有限元强度折减法相结合模式,对三维边坡实例的各种工况进行数值模拟,得到边坡的最大剪应变、最大剪应力出现的部位和数值大小以及边坡整体安全系数,由此确定边坡的薄弱带和潜在滑面,能客观反映边坡稳定性。Midas / GTS geotechnical numerical simulation software with a simple interface, before and after handling power and rock material model library, can meet most of the Failure mode for rocks and soil. The establishment and analysis for threedimensional numerical model of the slope engineering is much closer to the real situation, and the calculation results are relatively safer, tn this article, the software is combined with strength Reduction FEM, we can finish numerical simulation for three-dimensional slope working conditions of various examples. The parts in which maximum shear strain, maximum shear stress of the slope appears, and numerical size and the safety factor can be calculated. Trough the results the slope of the weak zones and potential sliding surface can be determined, which can objectively reflect the slope stability.
