Analysis of Settlement and Pore Pressure Induced by Cyclic Loading of Silo
Publication: Journal of Geotechnical and Geoenvironmental Engineering
Volume 124, Issue 12
Abstract
Examples of periodic loads applied on a soil layer appear in practice in the filling and emptying of a silo or a tank. This loading is not dynamic loading. This paper develops a solution to the consolidation equation with boundary conditions that are cyclic with time. Measurements of settlements of the Ca' Mello silo are compared with a case of sinusoidal loading. Good agreement is observed for the settlements. It appears that the pore pressure at the center of the soil layer is significantly larger than the amplitude of the applied load.
