接触式钻孔灌注桩成孔质量检测系统的应用

Application of Contact Style Bored Pile Quality Testing System

结合当前钻孔灌注桩成孔检测方法的不足,分析了接触式成孔检测系统的优点并对其测量原理和方法（包括孔深、孔径、沉渣厚度、孔斜几个方面）进行了详细的介绍。以天津某大楼钻孔灌注桩成孔质量测试结果为例,说明了该系统在保证成桩质量方面的有效性。

In connection with the lack of detection methods for hole bored pile,analysis of the contact hole detection system and the advantages of its principles and methods of measurement（including the hole depth,diameter,thickness of sediment,several aspects of oblique） were analyzed in detail.An example of inspection results for hole bored pile of a building in Tianjin is given.Practice shows that the method is of great significance.
