反射波法桩身完整性检测技术的探讨

Discussion about the Technique of Pile Intergrity test by reflected Wave Method

本文结合几个工程实例分别阐述了低应变反射波法的激振技术与传感器的选择 ,桩周土 (包括护壁 )对反射波测试的影响 ,浅部、深部缺陷的分析判断和处理 。

Combining with several practical cases,the technique of exciting vibration and selection of sensor are introduced for low strain reflected wave method in this paper.Those are discussed effects of soil around the pile to the measurement,analysis and judgement of shallow or deep defects and orientation of defects.
