    Ground Vibration Reduction Analysis of Pile-Supported Subgrade for High-Speed Railway Using 2.5D FEM

    A 2.5-dimensional finite element model (2.5D FEM) for predicting ground vibrations of the coupled track-pile-supported subgrade system was proposed. In the model, the equivalent pile wall approach was used to ...

    Ground-Borne Vibration Generated by High-Speed Trains on the Pile-Supported Subgrade Reinforced by Geogrid

    The pile-supported subgrade reinforced by geogrid is widely applied in the construction of high-speed railway in China. To investigate the ground-borne vibration of such composite foundations subjected to movi...

    Application of Hilbert-Huang Transform to the analysis of the landslides triggered by the Wenchuan earthquake

    A steep rock hill with two side slopes located at DK30+256 of National Road 213 was used as a prototype for analysis. The full process from initial deformation to sliding of the slope during ground shaking was...

    Improvement of pseudo-static method for slope stability analysis

    In this paper, two drawbacks of the traditional pseudo-static method (vertical slice method) in the slope stability evaluation have been studied. First, the sliding mass is divided into vertical slices accordi...
