Slope Stability Evaluation and Remediation in DHA Islamabad

Abstract

The most common problem of slope stability and landsliding is being faced by different societies of Islamabad and its vicinity for last many years with DHA Islamabad as one of the example.Issues like slumping of deep cuts/excavations and slope instabilities/seepage and settlement in DHA Islamabad are not only creating problems for construction work but however are also hazardous to human life. Slope instabilities/seepage and landslide safety is a major concern of DHA Islamabad nowadays.There are many steps required to achieve the above mentioned safety.This study presents evaluation and remedial measures for slope stability in DHA Islamabad. The reasons for these soil slope hazards can be attributed to the unengineered cuts by the contractors.There are however other reasons such as alteration in the stresses,perhaps by increasing shear stresses or decreasing the effective normal stress or by reducing the resistance to the movement perhaps by decreasing the shear strength of the materials within the landslide. Topographical data and material properties of soil is the backbone of safety analysis without which it is impossible to carryout any analysis.Therefore in this study an effort has been made to make a 3D model of understudy slopes in Globber Mapper,subsurface strata profiling by Res2DInv,carrying out standard penetration tests to study material properties followed by analysis of slopes using Roc science software.Indeed it was a real time project addressing real time issues recommending real time practical solution
