Abstract:

Due to the limitation of the traditional theory of soil pressure applied on retaining wall, the limit analysis theory and the energy theory are adopted to calculate the limit load of rigid retaining wall. For the calculation of the gravity retaining wall, the Coulomb's earth pressure theory and the energy theory are compared in this paper. The results show that the energy theory is more suitable for general calculation of soil pressure, and has more validity and applicability than the Coulomb's earth pressure theory.
