Rock and Soil Mechanics
Soil-water characteristic curve (SWCC) plays an important role in defining the hydro-mechanical behavior of unsaturated soils. Biochar has the properties of porous structure, high specific surface area and high adsorption. The hydraulic characteristics of biochar-amended soil may change due to the influence of natural environmental factors when applied as the cover layer of landfills. In order to study the effect of biochar content on the water retention behavior of biochar-clay mixture in full suction range, the suction of samples was controlled by vapor equilibrium technique (suction range 3–368 MPa), filter paper method (suction range 0–40 MPa) and pressure plate method …

Rock and Soil Mechanics
The traditional methods for determining the soil-water characteristic curve (SWCC) in the full suction range always takes several months. To better guide the engineering practice with the theory of unsaturated soil mechanics, the rapid determination of SWCC is particularly important. In this study, a rapid measurement method for SWCC in the wide (full) suction range was developed with the combination of pressure plate method, parallel filter paper method and dew point potentiameter method, and the proposed method was used to test two different soils. Results showed that: i) The experimental data of the parallel filter paper method and that of …
