APPLICATION RESEARCH OF LARGE DIAMETER PHC PIPE PILE SINKING TECHNOLOGY UNDER COMPLEX LIQUEFACTION FOUNDATION
With the continuous popularization of large diameter PHC pipe piles in foundation construction,how to ensure the pile quality and bearing capacity of pipe piles under complex foundation conditions has gradually become a more and more concerned issue for foundation engineering builders.Aiming at the complex infrastructure construction of terminal 3 of Taiyuan Wusu international airport,reasonable arrangement of compacting gravel piles,scientific design of parameters and pile driving technology of large diameter PHC pipe piles have successfully eliminated the liquefaction property of soil between piles,guaranteed the pile quality,and finally ensured the bearing capacity of large diameter PHC pipe piles under complex liquefaction foundation.
