Abstract

Geotechnical as well as geophysical investigation methods were used to provide information for the assessment of the subsurface soil at BOOSTER STATION proposed site at Wuntin Dada near Abubakar Tatari Ali polytechnic gate. Percussion drilling was used to drilled the boreholes to the depths of 4 m and disturbed soil samples were obtained from the boreholes for different laboratory tests at the site. Natural moisture content, specific gravity, Atterberg Limits, Triaxial tests and Permeability Test were conducted. Borehole numbers 1, 2 and 3 have percentages of fines less than 10 %, this indicates that the influence of fine content is negligible on their engineering properties. The grain size analysis of the samples indicates that the total fine content ranges from 1.5 - 20 %, Sand 52.5 – 86.8 %, and Gravel 2.9 – 46.0 %. These values account for the moderate permeability values (1.76 ×10-6 – 3.50×10-6). The OMC was 5.90 - 13.00 % while MDD range was 1.77 - 2.01 Mg/m3. The soils’ cohesion ranges from 8.0 kN/m2 to 75.0 kN/m2 and the angle of internal friction range between 25o to 35o. with these values, the range of computed bearing capacity was 222 – 1132 kN/m2. The results of particle size distribution analysis indicate that very negligible consolidation settlement should be expected. It finally concluded that the material is of high quality with regard to strength and the integrity of the foundation.
