声波透射法在输电铁塔挖孔桩基检测中的应用

Application of Cross-hole Sonic Logging in the Dug Pile Foundation Testing of Transmission Tower

文中介绍了声波透射法的原理、适用范围、使用要求、方法步骤及检测结果判断;以具体工程为实例,对输电铁塔挖孔桩基础完整性进行了无损检测,并根据检测结果得出桩身完整性结论。实践表明,该检测方法值得在输电铁塔基础检测工程中推广应用。

This paper introduces the principle,scope of application,usage requirements,method steps,and detection result judgment of acoustic transmission method;Taking a specific project as an example,the integrity of the pile foundation of the power transmission tower is nondestructive tested,and the conclusion of the pile integrity is drawn according to the test results.Practice has shown that this detection method is worth promoting and applying in the.
