On the basis of making it clear that laterization includes such three integrated stages as weathering, micro-granularity and soil formation of laterite, the thesis illuminates characteristics of Kunming laterite in chemical composition, physical mechanics, composition of granules, fractal dimension of granularity and the connection of granules. The experiment using soil reinforced agent to solidify the laterite shows that the mechanical traits of laterite have been improved because of its involvement, the best compact indicators and shear strength ones increased and the indicators of laterites penetrability and compression decreased. The effects of reinforcement can be weighed through its coefficient and the mechanism of reinforcement can find the explanation in the effect of soil reinforced agent on the laterite granules, the changes in the electric double layer caused by soil reinforced agent and its enwrapping of laterite granules.
