Abstract

A study is presented here at the future site of a pediatric hospital building complex near Bisrate Gabriel church, Southeast of Addis Ababa. Effort has been made by combining geophysical and geotechnical investigations to characterize the site for construction of a multistorey building. In this study,two test samples were taken for geotechnical investigation.The results showed that the soil has high content of clay minerals especially montmorillonite. The soil has high degree of expansiveness and high Atterberg limits. The shear strength parameters are very high. However, its shear strength decreases with saturation. Cohesion and angle of friction are 50 KN/m2 and 170 respectvively. The expansive soil has 1.33g/cm3 maximum dry density 25% optimum dry density. On the other hand,the soil contains high free swell value that is 175%. The investigation was consisting of geophysical survey (2D Electrical resistivity imaging and Vertical Electrical Sounding, VES). The geophysical investigation indicates that soil with respect to their resistive value in their respective profile. Site reconnaisance and soil samples are the methodologies used to characterize the soil.
