Study of Geotechnical Assessments for The Foundation and Construction of Civil Work at Tharparkar District, Sindh, Pakistan

Abstract

This study evaluates engineering properties of soils for the foundation in Tharparkar district. Three boreholes were investigated in the study area at the depths of 8m, 9m and 9m respectively. The area is mainly divided into three zones, i.e. BH-01, BH-02 and BH-03. Groundwater was not encountered in any borehole. The soil profile of all three boreholes are low dense to medium dense at 2.0m to 6.0m and the 7.0m to 9.0m depths respectively. Overburden depth was very dense (N-values ranges from 8 to 17 and 33 to more than 50 numbers). Laboratory results reveal that moisture content goes 4.8 to 6.4%, Soils are non-plastic in all three boreholes. The granular soils specify the angles of internal friction (ø) varying from 24⁰ – 33⁰ in respective boreholes; while in the collected samples granular soils have cohesion of 2.4 to 2.5kPa. According to AASHTO soil classification, the material belongs to the type of granular soil and in the group of A-3. Furthermore, finding of the examinations is robust for the development of structures, transmission line foundations and other civil works to observe the stability and quality of good foundation for the most part in Thar zone, particularly in the studied area.
