3-D numerical analysis of large subsoil liquefaction distortion influence resulted from earthquake on bridge pile foundation;

On application of composite pile foundation in bridge pile foundation construction in karst areas

At present,a comparative mature and unified calculation method of the cost of treatment of karsts cave in bridge pile foundation has not yet come into being in China,so there is a biggish divergence in the calculation method of costs between the owner and the construction enterprise.

By analyzing the displacement mode of unstable soil and the deformation mechanism of passive pile,an elastic perfectly plastic model and a hyperbolic curve model about the behavior of piled bridge abutment against soil lateral movements are developed on the basis of the previous research.

According to geotechnical literatures,the current research situation of embankment lateral effects on the piled bridge abutments on soft clay is analyzed.

By analyzing the displacement mode of unstable soil and the deformation mechanism of passive pile, an elastic perfectly plastic model and a hyperbolic curve model about the behavior of piled bridge abutment against soil lateral movements are developed on the basis of the previous research.

Research on Large Ground Displacement Effects on Bridge Pile Foundation under Earthquake Liquefaction and Improvements Techniques;

In this paper, on the basis of many studies reported in the literature, the effects on bridge pilesare reviewed of the liquefaction induced lateral spread and large ground displacements.

More and more study on cap-pile groups-soil interaction of bridge pile in loess area has been paid attention to.

Power-progression solution for inner-force analysis of bridge pile in steep slope;

The loading characteristic of bridge pile in steep slope is more complex to that of slide-resistant pile as the slope sliding,so an influence factors compassion model test is carried out based on the rational simulation of slide surface.
