Research on Foundation Pile Checking by Analysis and Comparison on Ultrasonic Transmission Method and Reflected Wave Method

摘要: 应用非金属超声透射法和低应变反射波法的基本原理，对不同缺陷的基桩进行对比试验，得到所检测桩的缺陷类型。根据研究结果，对这两种方法在桩基完整性检测中的优势和不足进行了探讨。指出两者的结合可避免缺陷漏检，提高基桩检测的精度。

Abstract: According to the fundamental principles of low strain reflection survey method and nonmetal ultrasonic transmission method, this paper will compare the experimental results using these two approaches in foundation pile examination aiming at confirming the pile defect type. After analyzing the results, this paper will introduce both advantages and shortages of these two methods in pile foundation integrality examination, thus suggesting that their integration could increase measurement precision. In practical use, the two approaches should better be combined in order to avoid undetected defect and ensure measurement precision.
