主要从施工工艺、挤土效应等角度进行阐述,分析了建筑工程PHC管桩裂缝的形成原因。提出了PHC管桩裂缝和断桩缺陷的处理措施,加强预防控制,选择合理打桩顺序,减小挤土效应。采取合适的的补救措施处理管桩裂缝和断桩缺陷,为工程建设夯实基础。 Mainly from the construction technology, squeeze soil effects such as angle elaborated, analyzed the cause of the formation of PHC pipe pile cracks. Proposed PHC pipe pile cracks and broken pile defects treatment measures to strengthen prevention and control, choose a reasonable sequence of pile driving and reduce squeezing effect. Take appropriate remedial measures to deal with pipe pile cracks and broken pile defects, laying a solid foundation for the construction of the project.
