| 摘 要： | 边坡稳定分析中常用的方法有极限平衡法和有限元法,而瑞典条分法由于其原理简明、公式简单而成为应用广泛的边坡稳定分析方法之一。但瑞典条分法忽略了土条侧面的作用力,并不能满足所有的平衡条件,由此算出的稳定安全系数比其他严格的方法偏低。本文是基于瑞典条分法做了适当的改进研究,从而提高了其计算精度。

| Abstract: | In slope stability analysis,the limit equilibrium method and finite element method are usually adopted.Because of the concise concept and the simple formula,Swedish slice method becomes one of the most popular methods for stability analysis of landslides.But it ignores the force on the flank of the vertical slice and can not meet the equilibrium conditions,so the result is lower than others.Some research into the improvement of Swedish slice method which has been done in this article makes the result more accurate. |
