摘要预应力高强混凝土管桩(PHC管桩)因其自身的优点越来越多地应用到实际工程中,PHC管桩通常采用静力压桩法进行施工。对于结构设计人员来说,仅掌握其结构设计是不够的,现实中常会遇到施工问题,如何及时解决这些问题对设计人员提出了更高的要求。对PHC管桩从结构设计、沉桩机理、施工单位反映的问题、认识上的误区、事故处理等方面进行分析,以期对结构设计及相关人员有所帮助。 Because of its own advantages,the prestressed high-strength concrete pipe pile(PHC pipe pile for short)is more and more used in practical engineering,PHC pipe pile is usually constructed by Jacked driving method.For structural designers,it’s not just enough to master the structural design,Construction problems are often encountered in reality,How to solve these problems in time puts forward higher requirements for designers.The PHC pipe pile is analyzed from the aspects of structural design,jacking mechanism,problems reflected by the construction unit,misunderstanding and accident treatment,which is in order to provide help for structural designers and related personnel.
