In this study, the contour of the soil arch is not assumed as a certain curve, and the soil stress analysis is conducted on a differential element with two dimensions. Herein, analytical expressions of the active earth pressure, active earth force are derived based on the static equilibrium of the differential element. Furthermore, the effects of wall-soil friction angle and soil internal friction angle on the active earth pressure are investigated. Eventually, comparisons among the proposed method of this study and the previous measured data and other analytical approaches yield satisfactory results.
