Abstract
The Static and dynamic rock slope stability analyses of the left and right abutments of the proposed Chenab (J & K, India) railway bridge were performed using the distinct element code UDEC for a 359 m high rock slope. The analyses have been carried out in three stages for predicting the behaviour of the rock slope. First, an initial static loading is applied in the numerical model. Second, weathering and interlocking conditions are modelled. Third, a dynamic loading is applied to simulate dynamic earthquake conditions. Various monitoring points were installed in the model for critical observations. The displacements and velocity values observed confirms the stability of the rock slope. The study provides an illustration of how the geo-mechanical properties of a rock mass can be integrated in a discontinuum rock slope model. This model has helped to better understand the dynamics of the rockslide when subjected to static and dynamic loads.
