| 摘 要： | 瑞典条分法是进行边坡稳定分析的一种经典算法，但其计算过程较为复杂，特别是在进行最危险滑弧的搜索时，每给定一个新的滑弧，都要重新进行条分。采用积分法对瑞典条分法进行改进，将瑞典条分法的稳定系数简化成一个一元函数，使得在计算稳定系数时不再需要进行条分，简化了稳定系数的求导过程，也改进了最危险滑弧的搜索过程，更加有利于电算程序的编制。 |
| 关 键 词： | 瑞典条分法 积分法 稳定系数 |

| Abstract: | Sweden method of slices is a classical arithmetic in slide stability analysis, but its' accounting process is comparatively complex that we must do new slices for a newly given sliding arc when searching the most dangerous sliding arc. The improvement of Sweden method of slices in this text is realized by a integral method which simplifies the stable coefficient of Sweden method of slices to a unitary function that we need not to do slices when counting the stable coefficient. This method simplifies the counting of stable coefficient and improves the searching of the most dangerous sliding arc, so it's propitious to weave electronic accounting program. |
| Keywords: | Sweden method of slices integral method stable coefficient |
