  On the D evelopmen ta l Tendency of PHC Concrete Pipe Pile
  Liu Jinyu  Liu Minghong
  Abstract: The authors discuss the advantages of the pre-stressed highly intensified concrete pipe piles and the advanced technology of the static pile foundation by comparing the common pile foundation methods. Meanwhile,the authors make a complete analysis of their reliability and economy,and thus come to a conclusion that of the various pile foundations,the p re -stressed highly intensified concrete pipe piles come out first.
  Key words: PHC Concrete pipe pile; Endurance; Credible quality; Economic effectiveness
  1、PHC 管桩简介 预应力高强度混凝土管桩代号为PHC (简称PHC 管桩)[1]。是采用先张预应力离心成型工艺,并经过10个大气压、1800 ℃ 左右的蒸汽养护,制成一种空心圆筒型混疑土预制构件,标准节长为10m ,直径从300mm~800mm ,混凝土强度等级≥C80。PHC 管桩的常用规格及适用范围如表1所示[2] 。表1  PHC 管桩的常用规格外径(mm )壁厚(mm )承载力标准值( kN )适用楼层
