Abstract： Bridge is one of the important components of highway and railway construction. In the new period， the rapid economic development of our country needs to do a good job of bridge construction. Bridge pile foundation is an important foundation of bridge construction， and its construction quality directly affects the quality of bridge construction. In order to do well in the construction of bridge pile foundation in addition to the construction quality， it is also necessary to actively check the bridge pile foundation in order to check the possible defects and hidden dangers of the bridge pile foundation. Ultrasonic testing technology is an important technology applied in the construction of bridge pile foundation concrete. The integrity and strength index of bridge pile foundation concrete can be realized by using ultrasonic detection technology. Thus， it can provide reliable data guarantee for the construction of bridge pile foundation and the inspection and acceptance. On the basis of analyzing the characteristics of ultrasonic testing technology， this paper analyzes and expounds its application in bridge pile foundation concrete detection.

橋梁桩基础主要用于承担桥梁的重量，在桥梁的建设中应当积极做好桥梁桩基的施工与性能检测，用以确保桥梁桩基的施工质量。超声波检测技术通过应用于桥梁桩基检测时能够实现对于桥梁桩基的无损检验，在保障对桥梁桩基检测质量的同时提高了对于桥梁桩基的检测效率。

1 超声波检测技术应用于桥梁桩基检测的原理

超声波检测技术应用于桥梁桩基混凝土的检测根据桥梁桩基混凝土结构形式的不同主要分为回波法和透射法两种检测方法。回波法能够在内部介质较为均匀的桥梁桩基混凝土检测中取得较为良好的检测效果，比如说桥梁桩基内部主要为金属介质的桩基。……
