The expansive soil is characterized with the moisture change induced swelling and drying shrinkage, which may further lead to the crack propagation, and the strength, permeability and deformation properties of expansive soil are generally influenced by crack patterns. Based on the elasticity theory, the moisture change instead of matric suction was adopted to analyze the stress state and deformation properties of expansive soil, and the analytical solution of moisture- change induced stress was deduced with the consideration of moisture change. The initial cracking model based on moisture change was established in combination with the static equilibrium and the shear strength theory of saturated soil. The analytical expressions for the depth, spacing and width of initial cracks induced by water loss were achieved, and furthermore, the proposed model was validated by the test results of crack propagation. The sensitive analysis was also conducted for the relationships between spacing and width of initial cracks and elasticity modulus, shrinkage coefficient, distribution coefficient of moisture change and cohesion etc. of soil.
