Profiling and Zoning of Geotechnical Sub-soil Data Using Geographic Information System

This research paper presents a compendium of the geotechnical sub-soil data profiling and zoning of the major urban settlements of Peshawar using Geographic Information System. Significant geotechnical properties of the under study area soils i.e., Zone 5 & 6 in Peshawar were assessed through one hundred and three different standard penetration test reports up to the depth of 1 m and 3 m. The qualitative description of the sub-soil data was manipulated into the quantitative figures by means of coding in order to interpolate the soil class distribution for the preparation of geotechnical zonation maps. This work is helpful for balancing of cost and acquiring the significant reliable data regarding soil class distribution, classification charactrestics, shear strength charactrestics and bearing capacity of soils during feasibility and preliminary design stage of the project.
