摘要
针对低应变反射波检测法在PHC桩完整性检测中的局限性,阐述了基桩孔内摄像技术的原理及应用,并通过工程实例证明了该技术具有直观、精确、可进行定量分析等优越性。
The limitation of low-strain pulse echo method in the PHC piles testing are analyzed, and the principle of the method with video monitor through the hole of foundation, and the application of the instrument are introduced. The advantages of this method such as objective, precise and capable of quantity analysis are preveded with some engineering cases.
