基桩超声波法作为完整性无损伤检测的重要手段,能准确测出混凝土灌注均匀性及强度等级等性能指标,从而确保桥梁桩基结构安全。现主要通过观测和分析声波在混凝土介质中的传播参数与桩体强度的相联关系,综合混凝土声学参数临界值、PSD判据,对利用超声波法检测桥梁桩基缺陷和完整性的原理和检测步骤进行探讨。
Piles ultrasonic method as an important means of integrity without damage detection, can accurately measure the concrete perfusion uniformity and strength grades and other performance indicators, thus ensuring the safety of the pile structure of the bridge. Now mainly through the observation and analysis of sound waves in concrete medium propagation parameters and the relationship between the strength of the pile, integrated acoustic parameters of the critical value of the PSD, PSD criteria, the use of ultrasonic method to detect defects and integrity of the bridge pile foundation principle and testing Steps to explore.
