LI Xin-xing, LIN Yong-liang, ZHU He-hua, et al. Unified solution for earth pressure on a rigid retaining wall rotating about base[J]. 2006, 27(S2).DOI:
It is known that the distribution of the active earth pressure against a rigid retaining wall is not linear but nonlinear. Based on the unified strength theory
the formulations of the unit earth pressures
the resultant earth pressure and its acting point are given for the wall rotating about the base by analyzing the slice elements extracted from the sliding soil wedge. The formula takes account of the effect of intermediate principal stress. It is demonstrated that the strength theory has great influence on the earth pressure; and the potential strength of the filling materials is sufficiently developed under the guidance of the unified strength theory.
