AbstractSlope failures endanger the public safety and one of major hazard considered in mountainous terrain. In this paper, slope stability measures have been evaluated using the limit equilibrium method (LEM). A case study of slope failure from Birham land slide, Murree, Pakistan has been modelled using SLOPE/W program. In-situ boring tests are performed to collect laboratory test specimens. Geotechnical properties (i.e. shear strength and stiffness parameters) for the idealised slope sections are based onlaboratory tests performed on the collected in-situ specimens. Slope stability measures are evaluated in terms of factor of safety (FoS) for static and dynamic loading. Pseudo-static method is used for dynamic analysis, considering the Peak ground acceleration (PGA) from seismic hazard map of Pakistan. Results shows that static and dynamic FoS of original slope are inadequate therefore resistance to slip surface of original unstable slope is provided by slope geometry modification with pile reinforcement. Based on these remedial measures, computed FoS of modified slope are found to be sufficient for static and dynamic slope stability. © 2018 Institute of Physics Publishing. All rights reserved.
