Abstract
  • The usual approach to calculation of the ultimate bearing capacity of plastic silt is to assume no porewater drainage occurs during the loading period. The coefficient of permeability of plastic silt is generally significantly larger than clay; therefore, partial drainage of porewater may occur during the loading period. This study evaluates the validity of the no porewater drainage assumption as it applies to a particular plastic silt. A series of plate load tests were performed on three circular footings of different sizes, placed on the bottom of a shallow excavation. Ultimate bearing capacity for each footing is interpreted from load-settlement curves. Samples were taken from the test pit and the shear strength was evaluated by laboratory testing. The shear strength is used in the Terzaghi, Meyerhof, and Hansen bearing capacity equations. Bearing capacities calculated using the no porewater drainage assumption and local shear failure conditions yield the best correlation with load test data.
