摘要： 不平衡推力法广泛应用于滑坡控制设计，抗滑力设计按照不平衡推力取值，但计算所得稳定系数未指明在不同方向的稳定程度，也没有指出不同方向的抗滑力的取值大小。在分析传统稳定系数的基础上，指出了传统稳定系数的缺点，应用多参量稳定性评价指标，分析了咸宁市咸安区舒上滑坡在不同方向的稳定特征，提出了滑坡稳定分析的分项系数设计方法和滑坡控制措施的布置位置确定，也提出了控制措施的强度和刚度要求、抗滑力的取值方法和不同方向稳定系数设计要求。治理措施经多年运行结果表明，该分析和控制设计方法是正确的。

关键词: 滑坡, 多参量稳定分析, 分项系数设计法, 控制措施

Abstract: The unbalanced thrust method is widely used in the control design of landslide, and the anti-sliding force is taken based on the unbalanced thrust. But the calculated stability coefficient does not indicate the stability degree in different directions, and the value of anti-sliding force in different directions is not also given. Based on the analysis of the traditional stability coefficient method, the shortcomings of the traditional stability analysis are raised. The partial coefficient design method of the stability analysis of landslide is proposed by using the multi-parameters stability index. The stability characteristics in different directions of a Shushang landslide in Xian’an District of Xianning City, Hubei Province are analyzed by using of the multi-parameter stability evaluation index. With the field investigation and survey, the corresponding control measures are formulated with the help of the layout position of anti-sliding measures, the value selection method of anti-sliding force and the partial coefficient design method proposed in this paper, and the strength and stiffness requirements for control measures have also been suggested. The results show that the location selection of control measures, the determination of anti-sliding force and the partial coefficient design method of the landslide are feasible after years of operations. 

Key words: Landslide, Multi0Parameters Stability Analysis, Partial Coefficient Design Method, Control Measures
