Abstract: Based on the elastic foundation beam method this paper presents the ideas of back analysis of m constructive process, i.e., a construction process of excavation and support in stage is introduced into the common back analysis, and providing reliable guarantee for predicting the deformations in succession construction stages. Grounded on the incremental measured datum between two arbitrary stages, such as the horizontal deformation of retaining structures, and by use of the back-analysis method of FEM and simplex optimization techniques, the elastic models of several layers of soils are calculated and back-analysised. Finally the method is proved to be feasible to calculate and to predict the displacements of retaining structures on the basis of a deep foundation pit engineering.

Key words: m-method, retaining structure, back-analysis
