Abstract: The cracking behavior of expansive soil due to evaporation are analyzed qualitatively and quantitatively. The critical value of matrix suction for initial cracking is presented, which is according with results of the site test. With the linear elastic mechanics, the depth of initial cracking for expansive soil is put forward and the relations between the depth of initial cracking and soil parameters such as tensile strength, Poisson’s ratio and gravity density, are discussed in detail.

Key words: expansive soil, unsaturated soil, matrix suction, initial cracking behavior, surface evaporation
