跨孔超声波在钻孔咬合桩完整性检测中的应用

Application of the Cross-Hole Sonic Logging Test to Evaluate the Integrity of Secant Piles

摘要: 本文介绍了跨孔超声波探测技术的原理、探测流程和解释方法，并以阿曼拉斯玛卡兹原油储罐工程中使用跨孔超声波检测海水取水井钻孔咬合桩完整性的实例，指出其在混凝土灌注桩质量检测中发挥的作用，表明了跨孔超声波检测操作方便、准确率高、经济性高等优点。

Abstract: This document introduces the cross-hole sonic logging test principle, methods and interpretation. Based on practice at Ras Markaz Crude Oil Park Project in Sultanate of Oman, cross-hole sonic logging test is used to detect the integrity of concrete secant piles for seawater intake well, which points out its role in concrete quality control for cast-in-place pile, and demonstrates that the cross-hole sonic logging test method is highly efficient, accurate, and costless.
