One-dimensional compressibility and shrinkage behavior of an initially saturated clay

Tóm tắt

This paper presents the experimental study on onedimensional compressibility behavior, soil water characteristic and soil shrinkage behavior of slurry Amberger kaolin. Soil water characteristic curve (SWCC) (Sr-ψ) was determined using conjunction between SWCC (w-ψ) and soil shrinkage curve (w-e). The oedometer test was performed with a maximum applied vertical stress of 6.4 MPa. The volume change behavior of sample due to the suction and that due to applied vertical stress demonstrated a similarity within the saturation domain.
