Propagation characteristics of transient waves in low strain integrity tests on cast-in-situ concrete thin-wall pipe piles;

Analytical solution of dynamic response of cast-in-situ concrete thin-wall pipe piles under transient concentrated load with low strain;

Study on the treatment of floating of static pipe piles;

Key points of quality management in the production of tubular pile as well as the suggestion on the establishment of industry supervision;

Technology and application of tubular piles back grouting

Soft soil foundation reinforced by tubular pile is a type of rigid cushion composite foundation under flexible base,and it is different from flexible cushion composite foundation under rigid base.

Causes of breakage of tube pile and practical study on rectification-joining method;

An application of sinking Pile of dilling to lead the hole in solving the broken pile of the tube pile;

Due to the difficulty of construction quality control,application of tube pile foundation has been restricted in limestone zone.

Introduction to building material standard of silica powder for prestressed spun high strength concrete pile;

On technical regulation for DBJ 04-273-2009 prestressed concrete pile foundation

The settlement behavior in open-end and close-end piles was discussed in this paper based on the force-settle-ment test with eight specimens.

Dynamic and static comparative analyses of settlements of overlength PHC pipe piles;

Based on the field tests data of five pipe piles, this paper studies mathematically the relationship between pile peak loads and pile peak settlement, as well as the bearing behavior of steel pipe piles in terms of the relationship between pile shaft compression and pile peak loads.

To reveal the performance of the large-diameter pipe piles under lateral loads,the nonlinear beha-vior of soil as well as the contact behavior of the pile-soil system are considered.
