Abstract: In order to calculate the active earth pressre or passive earth pressre under the inclined wall considering the soil arching effect, the two key factors, the coefficient of lateral earth pressure, and mean vertical pressure, which can decide the distribution of active earth pressure or passive earth pressure behind inclined wall and are derived based on the analysis of stress state behind the wall and the lateral differential elements method, are given as a unified formula. The unified solution of active earth pressure and passive earth pressure is used to calculate both the magnitude and point of application of total earth pressure. According to examples, the dip angle of inclined retaining wall has a different influences of soil arching effect on limit active earth pressure state and limit passive earth pressure state, as the dip angle increasing, the height of resultant active earth pressure would be decreasing due to that the influence of soil arching effect would be decreasing. On the contrary, as the dip angle increased, the height of resultant influence passive earth pressure would be increasing due to that the influence of soil arching effect would be increasing.

Key words: inclined wall, soil arching effect , active earth pressure, passive earth pressure, unified solution
