Balance Thrust Method on Stability Calculation of Retaining Wall

There are several problems in stability calculation method of retaining wall which has been widely used.The problems are:estimating the stability doesn't comply with the principles of mechanics by separating the components of acting force into two acting forces; the anti-overturning stability coefficent is uncertain due to the defects in its definition and the differences of the foundation's hardness,and repetitive with the linear eccentricity of the basement's join-force;it would cause the insufficient foundation bearing capacity that the active earth pressure is be used or the passive earth pressure is ignored.the balance thrust method is put forward so as to improve the stability calculation method of retaining wall in view of the existing problems.
