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.
