基于极限平衡法中应用较为广泛的瑞典圆弧法和毕肖普法基本原理，文章得出4个不同影响因子下的边坡稳定安全系数，进而采用灰色关联度法建立计算模型，运用M atlab程序对边坡稳定性的影响因素进行敏感性分析。结果表明：通过毕肖普法所得的安全系数普遍比瑞典法大；中心角、孔压系数、坡角、坡高的变化对瑞典法影响更大；对于2种方法，中心角的影响程度比孔压系数大，坡角的影响也比坡高敏感。灰色关联度克服了传统回归模型在因素分析时的缺点，能够准确对各影响因子进行敏感性评估，为边坡类工程设计与运行管理提供了依据。

Based on the fundamental principles of the widely used Sweden arc method and Bishop meth‐od ,the safety coefficients of slope stability under four different impact factors are obtained .T he com‐putational model is set up with grey correlation analysis and the impact factors sensitivity of slope sta‐bility is analyzed by using the corresponding Matlab program .The result shows that the safety factors obtained by the Bishop method are generally bigger than those of Sweden arc method ;the Sweden arc method is more sensitive to the changes of central angle ,pore pressure coefficient ,slope height and slope angle ;for both the two methods ,the influence of central angle is bigger than that of pore pres‐sure coefficient ,and the effect of slope angle is bigger than that of slope height .Grey correlation grade can overcome the shortcomings of the traditional regression model and evaluate impact factors sensitivity accurately ,w hich provides a basis for the design and management of the slope engineering .
