在极限平衡理论的基础上，考虑外部因素（水、拉裂缝、外荷载）与加固措施（锚杆、锚索、土工织物、土钉）对边坡的作用，推导出能模拟各种极限平衡方法的改进通用条分法（IGLE）理论体系，并编写了相应的计算程序-Rslope。运用改进通用条分法（IGLE）模拟了不平衡推力法，并对不平衡推力法（强度储备法）与不平衡推力法（超载法）的安全系数与剩余下滑力进行了精度分析，给出了使用建议。针对工程人员容易混淆剩余下滑力与条间力的情况，对条间法向力与剩余下滑力的水平分力进行对比分析，结果表面二者没有必然联系或者规律。运用Rslope程序与商品化软件slide、SLOPE/W进行了算例分析，对比了自动搜索圆弧滑面、折线型滑面、加固后的边坡安全系数，结果具有很好的一致性。

Based on the theory of ultimate equilibrium , an improved General Limit Equilibrium method (IGLE) is studied ,and it is implemented in Rslope software .IGLE can simulate various limit equilibrium methods and takes into account external factors (water、tensile crack、external load ) and reinforcing measures(anchor、anchor-cable、geotextile、soil nail) .Imbalance thrust force method is simulated in this study ,and analysis on precisions of safety coefficient and residual pushing force under two conditions of imbalance thrust force which are strength reserve method and overload method respectively by using IGLE is conducted . T he study also promotes an effective usage recommendation . Aiming at the problem that engineer is easy to confuse residual pushing force with inter-slice force ,comparative analysis on horizontal components of inter-slice force and residual pushing force is conducted .The results show that there is no direct correlation between them . Then the results of calculation examples of Rslope are compared with other commercial soft wares ,such as slide ,SLOPE/W .Specifically ,the comparison includes automatically searched safety factor of circular slip surface , safety factor of sliding surface and safety factor of reinforcement .The results have a good consistency .IGLE is of practical significance for real applications .
