| Abstract: | Based on simplified consolidation theory of unsaturated soils, the whole process of formation, propagation and close-up of cracks in clay surface during a drying and wetting cycle were simulated successfully in this paper. The computational results show that the proposed simplified consolidation theory of unsaturated soils is valuable to practical use. |

| Keywords: | clay drying and wetting cracks formation propagation close numerical simulation |
