Research aspects

1.Deformation rule of soft foundation and composite foundation in Expressway

2.Settlement calculating method of soft foundation and composite foundation in Expressway

3.Design method Controlled by the Deformation at transitional belt at end of bridge

4.Research on systemic and dynamic control method during constructing of expressway on soft foundation

Innovation

The key Research aspects are analysis of deformation and settlement calculating method.  By the use of back analysis method, which is on the basis of contrasting theory analysis and the observed settlement in situ, the theory of deformation analysis and dynamic control method during constructing of expressway on soft foundation will be acquired.
