采用FLAC3D研究某边坡的大变形破坏,模拟了边坡天然情况下的应力状态,分析了边坡分步开挖对边坡稳定性的影响,然后根据计算的结果对边坡采取了一定的加固措施,对加固后的边坡应力、应变状态进行分析,得出边坡基本处于稳定状态,分析表明,FLAC3D在解决边坡的大变形模拟方面的优势是有限元无法比拟的。
Abstract：Some slope is studied by use of the program FLAC 3D. The stress state f or the initial slope is simulated.The effect of step excavation to the slope is analyzed.According to the result,some measures are taken to improve the stab ility of slope. After that,the stress and the strain of reinforced slope is ana lyzed.The result shows the slope is stability. By contrast to the finite elemen t method,it is good to solve the large scale deformation of the slope for the p rogram FLAC 3D.
