Abstract

On a method for safety control of retaining wall, this paper proposes a back analysis based on inverse formulation method with simple model to estimate unknow parameters (such as lateral pressures acting on retaining wall and elastic constant of soil) more quickly and more stably at construction site. And after investigation with some calculation examples about the validity of this method, it is verified that practical solution of wall displacements and axial forces can be gained. Finally, compared with measurement data, it is shown that the result of prediction analysis based on these assumed parameters is on the safer side.
