声波透射法在桩基检测中的应用浅析

Analysis in the application of sound transmission method in the monitoring of pile foundations

结合声波透射法检测原理,介绍了判断混凝土质量的声学参数和影响声波透射法检测基桩质量的因素,针对钻孔灌注桩施工中易产生的缺陷,具体阐述了三种判断桩身有无缺陷的方法,并对常见问题或故障的处理进行了探讨,以期提高桩基检测的准确性。

Combining with the monitoring principle of the sound transmission method,the thesis introduces acoustical parameters used to judge the quality of concrete and the factors influencing sound transmission method to monitor the quality of pile foundations.Aiming at the shortcomings that can easily emerge in the construction of bored poured piles,it illustrates three methods to judge if there are big shortcomings in the body of the piles in details,and discusses the common problems or breakdown,so as to raise the accuracy of the monitoring for pile foundations.
