Abstract
This paper focuses on characterizing the deformation of consequent slate slopes in Taiwan. Onsite surveys, terrain analysis, and a physical model test are used to describe the characteristics of gravity-driven deformation under various conditions and identify the process of slate deformation as well as potential failure mechanisms. Slate deformation is shown to begin in the tension zone at cliff tops, wherein the slope body slips along the highly inclined foliation, contributing to shear failure or composite failure near the eroded zone of weakness. The phenomenon of foliation opening is widespread within the area of deformation, enabling surface water and groundwater to seep in, thereby accelerating deformation and failure in the slate deformation zone.
