| 摘 要： | 本文将非严格平衡条分法与严格平衡条分法中的各种方法都综合成统一公式。统一公式是两个代数方程 ,非严格条分法只需解一个方程 ,严格条分法解两个方程 ,不仅便于编程 ,而且计算简单、准确。通过分析比较 ,说明瑞典法、不平衡推力法都是极小值解 ,稳定安全系数最小 ;简化Bishop法稳定安全系数高出瑞典法 6～ 7% ,而严格条分法中的Spence法的稳定安全系数高出简化Bishop法的 2～ 3%。 |
| 关 键 词： | 极限平衡法 条分法 稳定安全系数 |

| Abstract: | The various methods from un strict equilibrium slice method and strict equilibrium slice method are synthesized and a unified formula has been obtained. The united formula consists of two algebraic equations. There is one equation needed for the un strict slice method and two for the strict slice method, so it is easy to program and give simple and accurate calculation. The results show by the analysis and comparison, that the Swedish method and un equilibrium thrust method give low limit value with the least stability safety factor. The stability safety factor by the concise Bishop method is more by 6 7 percent than that by the Swedish method and the stability safety factor of Spence method is more by 2 3 percent than that of the concise Bishop method. |
