| 摘 要： | 在土坡稳定性计算中，条分法作为一种简单而又实用的方法在实际工程中得到了广泛的应用。传统的条分法大多采用垂直条分，等圆心角斜条分法以斜条分代替垂直条分，使得条间力的假设更为合理。在斜条分的基础上，结合重新定义的应力水平安伞系数，使问题的求解也更为简单、迅速，并且求解的结果还可以反映出土条应力状态的差异。 |

| Abstract: | For calculation of soil slope stability, the slice method as a simple and practical method is widely applied to many engineering projects. The traditional slice method usually adopts vertical slice, while the slice method based on gradient slice and equal central angle adopts gradient slice, which makes the hypotheses of forces between the slices become more reasonable. Besides, with the redefined stress level safety factor, equilibrium equations can be solved more simply and quickly, and the differences of slices’ stress state will be reflected in the calculated result. |
| Keywords: | gradient slice equal central angle stress level safety factor soil slope stability |
