摘要
阐述了桥梁桩基缺陷检测技术发展概况,分析了跨孔声波透射法的基本原理。对不同类型桩身缺陷判断方法进行阐述,结合实例对钻孔灌注桩桩基采用跨孔声波透射法进行完整性检测,经验证说明桩顶以下62 m^66 m存在缺陷,并进行了加固处理。
The development of bridge pile foundation defect detection technology is expounded,and the basic principle of crosshole acoustic wave transmission method is analyzed. The method of judging different types of pile body defects is expounded. The cross-hole acoustic wave transmission method is used to test the integrity of the bored pile foundation. The verification shows that there are defects from 62 m to 66 m below the pile top and reinforcement treatment.
