摘　　要：本文指出了在微机上进行边坡稳定三维非线性有限元分析存在的困难，探讨了解决这些困难的方法，研制了一个能处理一般非线性问题，能模拟岩石性态、具有前后处理功能并便于在微机上运行的三维有限元分析程序，得到了一些有意义的结果。In the paper, the authors show that there are mainly four difficulties in 3-Dimensional nonlinear finite element anglysis for slope stability with personal Computers and approach the ways to overcome them. A FORTRAN programme which is suitable for personal computer for 3-Dimensional nonlinear analysis has been made. The pregramme is of the functions to solve ordinary nonlinear problems, to simulate the properties of slope rock masses and to sort out the date for the calculation. At the end, the authors calculate on a actual slope at Dexing, Jiangxi Province with the programme and obtain some significant results.
