Abstract: The traditional theory of soil mechanics considered that the preconsolidation of soil was controlled by the pressure force and stress history. However, based on the experimental results, the rule of the preconsolidation of red clay that is territorial peculiar soil is different from the traditional theory. The studies show that, the preconsolidation of red clay is most constrained by soil genesis, structure and component, and is affected by the overlying pressure in little degree. Finally, the defect of traditional soil mechanical view on red clay is analyzed; and the genuine signification of preconsolidation pressure of red clay was studied; and the new understanding about the preconsolidation is presented.

Key words: red clay, soil mechanics, preconsolidation, compression curve, structural strength
