Wedge Failure Analysis of a Rock Slope in Himalayas
This paper presents the wedge failure analysis at different pier locations for a railway bridge proposed at about 350 m above the ground level, crossing a river and connecting two huge rock slopes in Himalayas, India. The site is located in a highly active seismic zone. Static and seismic slope stability analysis confirmed the global stability of the slope. However, the rock slopes are highly jointed and the joint spacing and orientation are varying at different locations. Hence it is very likely that there could be wedge failures possible at some of the pier locations. This paper presents the results from kinematics of right abutment slope for the wedge failure analysis based on stereographic projections. Some very important conclusions regarding the local stability of the slope at various pier locations and field observations are presented with appropriate recommendations.
