管波探测法在岩溶勘察与基桩检测中的应用

Application of Tube Wave Method in Karst Investigation and Pile Detection

摘要: 本文介绍了管波探测法基本原理与数据采集、处理、解释的基本方法；通过工程实例表明：对于采用桩基础作为建筑基础的岩溶发育地区，采用“一个钻孔 + 管波探测法”的方式进行施工勘察与基桩质量检测，可弥补“一孔之见”的不足，避免基桩半边嵌岩及桩身质量误判，使建筑物安全和稳定性更有保障；管波探测法在岩溶勘察与基桩检测中具有良好应用前景。

Abstract: This paper introduces the basic principle of the tube wave detection method and the basic method of data collection, processing and interpretation. Through the engineering example, it is shown that the method of “one borehole + tube wave detection” can be used for the construction investigation and pile quality detection in the Karst development area where pile foundation is used as the building foundation, which can make up for the shortage of “one hole view” and avoid the rock socketed in half of the pile and the pile body. The misjudgment of quantity ensures the safety and stability of the building, and the tube wave detection method has a good application prospect in Karst investigation and foundation pile detection.
