| 摘 要： | 在瑞典园弧法的基础上,使用动、静两套坐标系的变换关系,首次建立了均质(多折坡)土坡稳定安全系数的解析函数表达式,运用函数极值原理,导出了求解均质土坡最小稳定安全系数的非线性方程组,并将整个求解过程用Fortran语言编成程序,在IBM及兼容微型计算机上计算了部分算例,取得了比较满意的效果。

| Abstract: | On the basis of Swedish slip-circle method, the transformation relation between the fixed and the kinetic of Cartesian coordinate system is applied to form the analytic function of the stability factor about homogeneous soil stepped slopes. The minimum stability factor obtained using maximum principle is described in detail in this paper. The paper presents the nonlinear equations and their solution procedure derived from the stability factor function. The solution procedure is compiled to computer program by FORTRAN Language. Several examples show that the results are satisfied and the procedure is easy to be programmed in microcomputers. |
