Shear Strength Properties, and Bearing Capacity of Coastal Plain Sands in Uyo Metropolis, Akwa-Ibom State, Southeastern Nigeria

The significance volume of the soil inside Uyo municipality in Southeastern state of Akwa Ibom was examined in this place study. The soil belongs to Coastal Plain Sand frequently named the Benin Formation in the study of land of Niger Delta. Both Field and Laboratory means were working in the study. The field system comprised Cone Penetration Test (CPT) accompanying a 2.5 heap Guada Dutch circular-shaped object with pointed end penetrometer, and the Light pressure penetrometer LRS 10. For the CPT, insight of inquiry was unwillingness insight that changes from about 9.0 m to 20.0 m. The wisdom of survey for the LRS 10 was not in addition to 6.0 m. The direct limit the LRS 10 evaluates is the relative bulk. Soil reflecting accompanying the LRS 10 recorded for all the sites a ‘unconstrained to medium’ constancy. No thick or very thick layer was met. The Laboratory procedure working was the direct clip box decision of united feature and angle of shearing fighting of the soil, that is to say the C- ∅ possessions. The union change very widely; accompanying a worth grazing from a nothing to 54 kN/m2. The angle of shearing fighting ranges from 8∘ to 30.7∘, accompanying as well ninety allotment dropping beneath 28∘, displaying a very compressible soil namely compulsive local cut disappointment. Bearing abilities is as reduced as 100.93 kN/m2 and as extreme as 571.1 kN/m2. Settlement guide reliable posture pressure supposed from CPT dossier categorized from 1.21 cm to 3.89 cm. while that from lab gives inferior principles, with making that from the field worth conservative.
