Abstract
Through combining with the Coulomb's earth pressure theory,the method of calculating earth pressure against rigid retaining wall under translation mode was studied based on the disturbed state concept(DSC).The disturbance function was established by taking the movement of rigid retaining wall as the disturbed parameter.The disturbed frictional angle concept was proposed and the relationship between the disturbed frictional angle and the disturbed degree was obtained.By analyzing the forces on the most unfavorable soil wedge at arbitrary disturbed state,the general formulas for calculating the earth pressure against rigid retaining wall under translation mode were established based on DSC theory.Calculation results shows that the predicted magnitude and distribution of earth pressure and the coefficients of earth pressure agree well with those of the model test at random disturbed state.
