Passive earth pressure on retaining walls calculated by principle of soil arching effect
a stress of wedge soil between rigid retaining wall and sliding surface
which is in the passive state of limit equilibrium
is analyzed. Considering the horizontal equilibrium of the soil between the wall and the slip surface
the formula of passive earth pressure coefficient and the angle of failure line to horizontal are obtained by using the principle of soil arching effect. According to the equilibrium equation considering the static equilibrium conditions of horizontal unit of soil
the formula of the passive earth pressure distribution
the resultant earth pressure and the application point of resultant earth pressure on retaining wall are respectively set up. After comparing the computed result using the method mentioned above with the experiment results and the results obtained on the basis of Coulomb and Rankine theories
it is demonstrated that the calculating results agree well with the experimental results; and thus the calculating method obtained is verified rational.
