MODELLING PORE WATER PRESSURE ON VERTICAL CONSOLIDATION INFLUENCED BY RADIAL FLOW IN HOMOGENOUS SILTY AND FINE SAND FORMATION IN COASTAL AREA OF PORT HARCOURT.

Pore water pressures on vertical consolidation in silty and fine sand formation were found to be influenced by radial flow. These conditions developed different settlement on some soil formation; this can be observed on the accomplishment installation of a system in vertical drain sand. This condition on sand drain essentially consist of a vertical borehole put down through the saturate fine grain soil by extension relatively to bottom, such condition provide the presences of excess pore water pressure dissipated by both vertical consolidation and radial flow as this will definitely be in vertical direction. The development of such behaviour in the study location were express on physical process, mathematical model were developed to monitor the rate of pore water pressure on vertical drain under the influences of radial flow, the derived model generated theoretical values through its simulations, validation were applied to express the behaviuor of the system, both parameter developed a favorable fit, the study is imperative because soil engineers will definitely apply this tools in monitoring the deposition of pore water pressure in the study location.
