Abstract:

The calculation model of soil pressure displacement is established based on Mindlin strain solution, that the difference of soil pressure between the calculated state and the static state is considered as the calculated distributed stress. The limited displacement of soil under active state of plastic equilibrium and that of soil under passive state of plastic equilibrium are both obtained with th model. The calculation program is programmed according to the calculation model to analyze the regulation of both the limited displacement of soil under active state and that of soil under passive state from some key parameters, including inner friction, cohesive force, calculated depth and calculated width. The measured data from a mdel test is used to illustrate the validity and rationality of the proposed model. The model can be used for calculating of soil pressure with different limited values of soil displacements, so as to provide a theorical basis.

Key words: soil pressure, Mindlin strain solution, soil lateral displacement, limited state, correlativity
