超声波法在大直径深基桩检测中的应用

Application of the Ultrasonic Method in the Large Diameter Deep Pile Testing

大直径灌注桩在应用的过程中具有较为明显的优点，如承载力较高。但是，大直径灌注桩在应用的过程中也出现了成桩质量缺陷等问题需要解决。对此，利用超声波法对其进行桩身完整性检测，具有重要的现实意义。

In application, large diameter bored pile has such obvious advantages as higher bearing capacity. However, large diameter bored pile also has its quality defects and other problems to be solved. In this regard, A complete detection for the pile by the ultrasonic method has important practical significance.
