摘要
文章以深圳地区某项目旋挖灌注桩桩身完整检测为例,分析旋挖灌注桩水平裂缝的成因,并通过比较低应变法、高应变法、声波透射法、钻芯法及孔内摄像法,探讨多种检测方法在灌注桩水平裂缝检测方面的优缺点和适用性,以期为类似工程提供参考.
Abstract
Taking the complete detection of rotary digging bored pile in a project in Shenzhen as an example,this paper analyzes the causes of horizontal cracks in rotary digging bored piles,and discusses the advantages,disadvantages and applicability of various detection methods in the detection of horizontal cracks in bored piles by comparing low strain integrity testing,high strain dynamic testing,crosshole sonic logging,core drilling method and borehole imaging method,so as to provide reference for similar engineering.
