Abstract

Pore pressure measurements made during the preloading of a large oil tank on a deep deposit of soft clay are reported and analyzed. The piezometer data show that the excess pore pressure at a point in the subsoil increases linearly with the increasing surface load until a certain critical load is reached. Then the induced shear stress at that point reaches the shearing strength of the soil, and local yield occurs. Henceforth there is a pronounced increase in the observed rate of pore pressure built-up.

Field Observation of Pore Pressure in Soft Clay

Pore pressure measurements made during the preloading of a large oil tank on a deep deposit of soft clay are reported and analyzed. The piezometer data show that the excess pore pressure at a point in the subsoil increases linearly with the increasing surface load until a certain critical load is reached. Then the induced shear stress at that point reaches the shearing strength of the soil, and local yield occurs. Henceforth there is a pronounced increase in the observed rate of pore pressure built-up.
