Settlement calculation of rigid piled-structure embankment in high-speed railway

The Mindlin-Boussinesq uniting solution is used to calculate the additional stress, and the settlement is calculated with the method of e-lgp curve. And then, the calculation results are analyzed comprehensively by comparing with the existing calculation methods and the in-situ measurement data. The research results show that the limitation 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; and the settlement calculated by method of e-lgp curve is relatively close to in-situ measurement data, which can take the parameters of the rigid piled-structure embankment and stress history of foundation soil into consideration.
