AbstractThe moment of resistance method and the formulation method were proposed to calculate the stress distribution of the basement effected by the eccentric loads, and those 2 new methods were capable for various situations of the stress distribution calculation.The analysis demonstrates that the overturn stability evaluation method by calculating the moment of the wall address used in the past had its potential security risks. So a new method was proposed in this article combined with the basement carrying capacity to evaluate the overturn stability of the retaining wall with the calculation examples as further explanation.
