Strain and pore pressure development on soft marine clay

Dec 01, 2013· The soft marine clay tested in this paper is from Wenzhou, a coastal city in southeast China. This type of clay is typically 30–100 m thick and has been recognized as one of the most problematic soils in China because of its high water content, high compressibility, low permeability and low bearing capacity.
