Journal Title:Global Journal of Engineering Science and Research Management (GJESRM)
Abstract


The Study was carried out within Parts of Port Harcourt, Rivers State. investigations shows that the topsoil is underlain by a Firm to Stiff Sandy clay layer of low compressibility with cu > 50 KN/m2 (about 12m thick) with average Index Properties which indicates average shear resistance to shear deformations. Also Cone Values within this layer reflects values greater than 10kg/cm2 with friction ration > 3 at the top layer. This layer , overlies a well sorted ,Medium Dense sandy Layer ( phi=300 - 310 ,) and average N Values of 12.. The allowable bearing capacity profile of the sub-surface shows average bearing Capacities characteristics( 1.5m:133KN/m2 ,). Compressibility of the top soil under the influence of load from Pressure Bulb analysis , indicates Compression Index and Compression Ratio value less than 0.1.. Settlement predictions based on a loading >200KN/m2 indicates a tolerable settlement of
