Abstract:

Soils structure is the essential intrinsic factor that it decides mechanics characteristics of soils. It is an effective method that the researches of soils structure characteristic are based upon the theory of comprehensive structure potential. This method not only can consider the characteristics of the soil particle arrangement (i.e. the geometric feature of soil structure) and the soil particle linkage (i.e. the mechanic feature of soil structure), but also can general, holistic, dynamic quantify soils structure characteristic. The soils structure parameters have been summarized and reviewed comprehensively in this paper, consequently the naming of structure parameters has been unified. The current situation of the relations between strength or deformation and structure parameters, constitutive models of structure parameters, application of structure parameters have been generalized. In the mean time the rational approaches and the influence for structure property and consolidated state to strength and deformation of soils have been analyzed. A new method that the strength and deformation should been studied in the condition of same structure parameters is proposed.

Key words: intact soils, structural characteristic, comprehensive structural potential, structural parameters
