Abstract
This paper presents an analysis of the deformation mechanism and stability assessment of a slope in Yunnan Province, China. Field investigations indicated that the deformation of the slope was caused by the combined effects of the unfavorable topographical, geological and hydrogeological conditions and the placement of man-made fill. The stability of the slope was assessed by 3D numerical modeling which showed that the factor of safety of the slope was 1. 1 in the natural state but reduced to 1. 03 after fill was placed. Pile reinforcement was undertaken, which raised the factor of safety to 1. 27.
