| 摘 要： | 针对桩基超声波检测分析中常用的概率统计法和PSD判别法存在的主要问题，提出了应用概率论的逆概率原理分离缺陷信息与干扰异常的新方法，试验研究的对比结果表明，逆概率法与概率统计法和PDS判别法相比，判据明确，只要选择合适的先验信息，就能在干扰背景下分离超声波曲线中的有用强弱信息；此外，还不易引起缺陷漏判，在桩基混凝上质量检测中，是一种行之有效的解释分析方法．

| Abstract: | To solve the main problems of statistics-analysis and PSD-judging widely used in pile testing with ultrasonic technology, a new method that can be used to separate the defect information of pile and interfered signal with the principle of converse-probabilistic of statistic theory is put forward. Compared results of experiment research show that converse-probabilistic method is superior in application effect to statisticsanalysis and PSD-judging. It can separate useful information in ultrasonic curves from interfere background. In addition, it won't deduce fault's losing determination easiliy, and thus is a practical explanation and analysis method in testing pile concreate's quality. |
