| 结合统一强度理论根据数值法推导了土质边坡统一极限坡面曲线，在此基础上提出了一种利用统一极限坡面曲线与原坡面线间的位置关系定义土质边坡稳定性系数的新方法。对于均质土坡，利用极限坡面曲线法可以快速且精确的得到其统一极限坡面曲线和边坡安全系数。应用统一极限坡面曲线法对均质土坡算例进行稳定性系数计算，得到的结果与已被验证方法的计算结果相吻合，表明本文方法计算结果是可靠的。此外，对多个均质土坡样本安全状态进行了判断，研究表明统一极限坡面曲线法计算得到的结果和已被验证的其它方法的计算结果吻合度较高，表明本文方法能够准确地判断均质土坡边坡所处的状态，而且吻合率优于其他方法，显示出统一极限坡面曲线法在判断边坡稳定状态方面的优势。同时分析了中间主应力对边坡稳定的影响，结果表明中间主应力对边坡稳定有较大影响。 |

| Combining with the unified strength theory，the process of soil slopes and unified ultimate slope curve is introduced by using a graph methodThen a new method to define soil slope stability coefficient with unified limit slope curve and the positional relationship of the slope lines was carried outFor the homogeneous soil slopes，the new method can be used to obtain the unified limit slope curve quickly and accuratelyThe results of stability coefficient of the homogeneous soil slope obtained are consistent with those obtained by the existing methods，indicating that the results obtained by the present method are reliableMeanwhile，the safety status of several homogeneous soil slope samples was also judged，the agreement rate by the unified limit slope curve method are higher than other methods，it shows the advantages of the unified limit slope curve method in judging the slope stabilityThe influence of intermediate principal stress to slope stability is discussed，the results show it has bigger effect on slope stability |
