Circular and catenary always represent the shapes of minor principal stress soil arch between two parallel walls, but which shape should be used in the calculation of active earth pressure on two parallel walls remains disputed. Considering fully developed wall friction or partially developed wall friction, circular and catenary, the two shapes of minor principal stress soil arch between two parallel walls are theoretically analyzed. According to the shapes of soil arch, the coefficients of earth pressure corresponding to different angle of internal friction and that of wall friction are obtained, and the formula of active earth pressure on two parallel walls is derived.
