在简要介绍钻孔灌注桩成孔检测与桩身质量检测现状的基础上,通过工程实例论述成孔检测与成桩检测之间的关联性,从成孔检测数据对低应变反射波法的辅助分析和成孔检测对超声波法的辅助分析两个方面,揭示了成孔检测数据对于桩身质量判定的重要作用。基于工程实际需要,从规范成孔检测本身及发挥成孔检测结果对桩身检测的辅助判定作用的角度,提出了建立成孔检测技术规范或规程的建议。
On the basis of a brief introduction of the status quo of hole injection and pile quality testing of bored piles, this paper discusses the relationship between hole detection and pile detection through engineering examples. From the data of hole detection to the assistance of low-strain reflection wave method, Analysis and Pore Formation Detection Two aspects of the auxiliary analysis of the ultrasonic method reveal the important role of pore formation data in determining the pile mass. Based on the practical needs of the project, from the perspective of standardizing the hole detection itself and taking the role of hole detection results into the auxiliary judgment of pile detection, a proposal is put forward to establish the technical specifications or procedures for hole detection.
