摘　　要：采用极限平衡理论中三种不同求解方法计算出不同条件下的土质边坡稳定系数,利用灰色系统理论中灰色关联分析方法,建立关联数据矩阵,计算各影响因素变化与边坡稳定系数之间的灰关联系数和灰关联度,确定出不同因素对土质边坡稳定系数变化的敏感性大小,可为边坡设计及滑坡治理等提供一定的理论依据。Three different solving method of limit equilibrium theory has been used to gain the stability factor of soil slopes under the different conditions. Using Grey Correlation Analysis Method of the Grey System,the matrix of correlation data is set up,the grey correlative factors and grey correlative degrees which respect to the influencing factor and the slope stability factor are computed,the size of the sensitivity of the differ-ent factors on soil slope stability coefficient changes are determined,which can provide certain theoretical basis for the design of slope and land-slide control etc.
