Fredlund and Xing (1994)'s equation is one of most popular equations in best fitting the soil-water characteristic curve (SWCC) data. It commonly considered that parameters such as a, n m are Cr an input value, which recommended to be1500 kPa or 3000 kPa. Based on analysis this paper, it observed setting be equal 1500 may downgrade performance SWCC data soils with a high air-entry value (AEV). ...
