预应力混凝土抗拔桩应用与展望

摘要

在预应力混凝土抗拔桩研究现状的基础上，总结分析了各类相关技术规程中抗拔管桩及方桩单桩竖向抗拔承载力的设计方法，针对桩身、接头、桩与承台的连接等方面的技术难点提出了相关建议，并介绍了该类桩型在实际应用中的关键问题及解决方法。%Base on the research status of prestressed concrete uplift piles, the design methods for uplift bearing capacity of piles and square piles in various related technical regulations are analyzed and summarized. Meanwhile, some suggestions on the pile body, joint and connection between pile and pile cap are put forward. In addition, some key problems of such type of piles and the solutions in engineering applications are recommended.
