The paper introduced the mechanism and the method of abandoned pile removing,and discussed the technology,equipment,construction effect and some relevant construction problems.

Development of control system of the wire saw for offshore discarded platform piles removal

3D finite element analysis of parallel seismic tests for integrity of piles of existing structures;

Analyzing the function of piles in composite foundations;

Study of the method for the determination of load bearing capacity of piles;

Fuzzy stochastic reliability analysis of pile foundation;

Numerical Analysis on the Effect of Creep and Discrepant Settlement on the Pile Foundation;

With the development of offshore engineering, pile foundation had been widely used in the offshore platform, port pier, etc.
