Analysis on Settlement Calculation of Rigid Piled-structure Embankment in High-speed Railway

Abstract:

The Mindlin-Boussinesq uniting solution is used to calculate the additional stress, and the settlement is calculated by method of e-lgp curve. And then, the calculation results are analyzed comprehensively by comparing with existing calculation method and in-site measurement data. The research results show as follows：limitations exists in the settlement calculation of rigid piled-structure embankment under embankment loads and over-consolidated or strong structural soil by the method of existing code; the Mindlin-Boussinesq uniting solution is used to calculate the additional stress of soil between piles in rigid piled-structure embankment, the distribution along depth can accord with the actual engineering situation on; and the settlement calculated by method of e-lgp curve is relatively close to in-site measurement data, which can take the parameters of the rigid piled-structure embankment and stress history of foundation soil into consideration.
