摘　　要：基于简化毕肖普法和瑞典圆弧条分法,研究了简单均质土坡和阶梯型均质土坡稳定性问题,提出在土坡总高度为定值情况下,调整阶梯型均质土坡各分级土坡高度不会引起土坡整体稳定系数的显著变化,将阶梯型土坡视为简单土坡计算并评价其稳定性。结果表明,简化后土坡的稳定系数较简化前小1%～4%,满足土坡稳定性分析要求。Based on simplified Bishop＇s Method and Fellenius＇s Method of Slices,the stability of simple and ladder-type homogeneous slopes is analyzed.If the overall height of the soil slope is constant,adjusting the height of the graded slope may not change significantly stability factor of overall slope.Taking ladder-type soil slope as simple slope,the stability results show that the stability factor of the simple slope reduces about 1.0 percent to 4.0 percent and it meets requirements of soil slope stability.
