Abstract

A huge number of slope failures have been reported following the 2005 Kashmir earthquake in Pakistan of magnitude 7.6. Thorough examination of disturbed slopes indicated that the rock is extensively weathered and lost its shear strength. Mechanism of weathering is repeated changes in temperature and moisture. Authors set to think about the geotechnical problems in near future from those slopes with a global approach and demystify the problem by delineating the thickness and mechanical properties of weathered layer exposed by slopes. Seismic refraction survey and intrusive tests indicated that the weathered layer has S-wave velocity range of 150–300 m/s and thickness is 1 m or its roundabouts. The in-situ information on geometry and mechanical properties of slope is believed to be a useful tool for the slope stability analysis.
