钻孔灌注桩成孔质量超声波检测法的问题探究

Study on the Ultrasonic Method for the Hole Quality Testing of Cast-in-place Pile

钻孔灌注桩的质量问题主要有成孔质量和成桩质量两方面,而成孔质量又直接影响到成桩质量。随着接触式仪器组合法在实际应用中受到越来越多的限制,新型的超声波测试方法将得到推广,对超声波测试技术的优缺点及其在实际工程中遇到的一些问题进行了研究。

The quality problem of the cast-in-place pile is mainly has two aspects of hole quality and the quality of pile,and the hole quality affects the quality of pile directly. As the instruments contractually inspection method in the practical application has received more and more restrictions,the new ultrasonic method will be promoted. In this paper,the advantages and disadvantages of the ultrasonic method and some of the problems in the practical engineering were studied.
