Computation Module of Expansive Soil Crack Depth Considering Dry-Wet Cycles
A model is developed for computing the expansive soil crack depth in this paper. By analyzing the process of moisture content changes, it is considered that the soil suction will increase when the moisture content changes, then the expansive soil contraction deformation occurs, but cracks will not appear until the soil suction arrives at the tensile strength. Under wetting-drying cycles, the soil strength reduces, the tensile strength and crack depth change, the effect of moisture content changing rate on matrix suction is analyzed, and the crack depth computation module is attained. The computation module applicability is validated through testing. The achievement of the model is important to determine the depth of water delivery and subgrade engineering.
