桩侧激振接收法在某在建厂房偏位承台下部基桩完整性检测中的应用
|
摘要
堆土不当造成某在建钢结构厂房独立承台发生明显的水平位移,进而导致承台下部桩基础可能受损。对于承台下部基桩的完整性检测,传统反射波法的激振接收方式不再适用。结合该工程实例,详细介绍了桩侧激振接收法的基本原理、现场检测、信号分析等内容,可以为类似工程提供参考。
Horizontal displacement of bearing platform of the construction in progress has been happened by ground heaped load,which may cause damage of pile foundation.However,for pile integrity testing of existing structure,the socalled reflected wave method of is no longer applicable.The improved method is suggested in detail by author, which has been successfully used in this engineering.The site of vibration signal excitation and receiving is pile side,which is different from that of traditional method.It may provide useful reference for similar projects.
