GEOTECHNICAL SITE INVESTIGATION OF FEDERAL UNIVERSITY DUTSIN-MA KATSINA STATE

Abstract


This study is a geotechnical investigation of the Permanent site of Federal University of Technology, Dutsin-Ma located in Katsina State. The soil sample was obtained from 10 trial pits and 10 SPT boreholes at 0.6, 2.1 and 3.6 m depths and all laboratory tests were conducted in accordance with BS 1377 (1990). The study is aimed at investigating the subsoil conditions based on geotechnical site exploration methodologies of soil samples and site data obtainment in order to take precise engineering decisions on the type of foundations suitable for the proposed structures, to determine the best depth of foundation embedment and best locations for different utilities. Plasticity indices values indicated presence of high content of fines and values of cohesion and angle of internal friction show that the shearing resistance and bearing capacity of soils will be relatively low. Allowable bearing capacity values in the range of 80 – 150 kN/m2 were found adequate for use in the study area with embedment depth between 1 – 3 m and raft or deep footings was recommended for story buildings in this study area.
