For a special engineering project, the effects of soil displacement induced by subway shield tunneling excavation on bridge pile foundation are studied using FLAC-3D.

Study on the application technology of high performance concrete in Qingdao trans-oceanic bridge pile;

In the paper,the design of the solutions for Xinghaijie station～Xinggangjie station shield-driven running tunnel crossing the piles of Hua bridge are presented,expatiations are made on the possible bridge pile treatment solutions in terms of technical feasibility,economical rationality and impacts on the surrounding environment and a solution most suitable for the project is selected.

In soft layers,because of the soil filling of approach roadbed,the soft soils are compressed and squeezed out laterally,resulting in the lateral pressure and the pile deflection in adjacent bridge piles and making the piles become passive ones.

A bridge pile project is an underground concealed one;the degree of difficulty for its construction is great.

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.
