Construction and development of PHC tube pile;

Application of jet grouting to treatment of PHC tube pile foundation on boulder mezzanine;

Elevated effect analysis of back-grouting on PHC piles;

Test study on dynamic properties of PHC pile;

Discussion on the results Comparison of static load test and High-strain dynamic test of PHC piles;

Through comparison,the static compression PHC tubular pile scheme is selected.

Through comparing static pressure of the PHC Tubular Piles the new guiding hole technology using the cement-soil pile to the normal technology for the static pressure of PHC tubular piles by the static loading test.

This paper introduces the construction technique and handled methods of the main technique problems of the PHC tubular piles, and the six typical examples encountered in construction course are listed and proofed.

Based on the study of vertical bearing capacity of sloping super-long PHC pile,considering the strength of pile body and soil at the same time,the FEM was adopted to calculate the vertical bearing capacity of sloping super-long PHC pile subjected to lateral soil movements.
