Effect of Permeability Coefficient of Reservoir Bank Slope on Pile Displacement and Ground Deformation

Abstract:

Due to effect of reservoir water, the deformation mechanism of reservoir bank slope has a great of influence to the buildings which locate on the bank slope. Considering the changes of permeability coefficient of ground, the deformation characteristics of bank slope ground and pile are analyzed based on the method of pile-soil interaction under the condition that the reservoir water level changing speed is invariable. The results revealed that the larger horizontal displacement of the ground and piles happened when the ground has a smaller permeability coefficient, and the larger settlement of the ground and pile happened, especially the pile which has greater differential settlement when the permeability coefficient of ground is larger. The results have certain reference significance on the safety evaluation and design of buildings which locate on reservoir bank slope.
