Abstract:
Based on twin-shear unified strength theory, the simplified calculation formula of twin-shear unified solution of space active earth pressure was derived when the earth pressure acted on retaining wall was taken as the spatial problem. The intermediate principal shear stress influence coefficient was discussed and the effect on active earth pressure and its parameters were investigated.The comparison with the existing reference was taken. The calculation results show that the earth pressure and its coefficient formula can be suitable for all kinds of different material behaviors; the space active earth pressure decreases with increasing of the intermediate principal stress influence coefficient; the coefficient of earth pressure and the vertical distance from the position of earth pressure to the top of retaining wall decrease slightly; good agreement can be observed from the comparison between the results of reference and that of this paper; a series of solutions can be obtained through transforming intermediate principal stress influence coefficient; the earth pressure can be determined by choosing suitable unified strength parameters in terms of earth behavior and practice situation in engineering application.
