Effects of water saturation and distribution on small-strain stiffness

Metadata Downloads
Abstract
The purpose of this study is to investigate the role of the degree of saturation and water distribution patterns on
small strain soil properties. First, we measure P- and S-wave velocities of fine sandsmixed with varying degrees
of water saturation Sw = 0, 5, 30, 60, and 100% during the vertical loading under zero-lateral strain conditions.
Next, we use a simple geometry analysis combined together with soil index properties to provide the firstorder
approximation of capillary pressure. Then, we consider the effect of capillarity on soil skeleton stiffness
to analyze the data in the context of Gassmann's framework. Finally, we investigate the effect of water distribution
patterns on small strain soil properties. Results showthatwater distribution pattern is a critical factor to control
the lowperturbation soil properties. Furthermore, a specific surface appears to be a good indicator to predict
the effective stress- and pore size-dependent capillary pressure in the determination of small strain geophysical
properties.
