Static and Dynamic Analysis of Rock Slope - A Case Study

Two dimensional plain strain distinct element method has been used to analyze a curved slope under static and dynamic loading condition. Most vulnerable cross profile of the slope has been selected through kinematic analysis and slope mass rating specially devised for curved rock slopes. Static loading has been induced in the model to simulate conditions of the prevailing rock mass. Again dynamic loading has been performed according to the expected peak ground acceleration in the area in order to simulate the slope mass condition during earthquake. According to kinematic result and slope mass rating, the slope is more vulnerable towards 70° face direction. Static analysis results an unstable portion at the base of the slope. The whole slope is unstable under dynamic loading and is expected to threat the region with the risk of rock fall as well as failure of slope.
