Saturation Effects on Initial Soil Liquefaction

Soil liquefaction has become an important consideration in the design of structures in seismically active regions. Many researchers have in the past attempted to determine the liquefaction potential of soils, but these studies concerned themselves with the liquefaction potential of fully saturated sands. In this paper, the writers establish a general relationship between the pore-pres-sure parameter, B and the initial degree of soil saturation, So. By introducing the experimental values of B obtained from tests on loose Ottawa sand.
