摘要
本文通过分析超声波检测混凝土灌注桩完整性的基本原理,探讨了能够表征混凝土完整性的超声参数及判断方法,并结合工程实例中的检测曲线图对比正常桩身与缺陷桩身的区别,分析缺陷区域进而提出缺陷区域的判定方法。在现场计算环境简约的条件下,提出了基于检测曲线更为便捷直观的缺陷判别方法,对提高混凝土灌注桩检测工作的效率提供一定的参考价值。
By analyzing the basic principles of ultrasonictesting the integrity of concrete piles, investigate the ultrasonicparameters which can reflects the quality of concrete and thejudgment method, Comparing the difference between the normaland defect pile body combining with engineering examples, Analyzethe defect area and then proposed the method of determininga defective area. Under the condition of poor computing at thescene of engineering field, proposed the detection method whichmore convenient and intuitive for the testing based on the detectioncurve, provide a reference value and practical significancefor the work how to improve the efficiency of the concrete piletesting.
