随着我国经济的飞速发展，社会的运作以及人们的日常生活已经离不开物流运输了。物流运输行业的飞速发展得益于道路桥梁建设方面取得的突破，因此提高道路桥梁工程质量对经济发展有着非常关键的影响作用。在桥梁工程中，很大程度上决定桥梁稳定性、强度和耐久性的就是桥梁的桩基，为此在桥梁建设中一定要把握好桩基的建设质量。在桩基混凝土的检测方法中，主要有超声波法、高应变动测法、低应变动测法、钻芯法这四种方法，其中超声波法以其综合优势和特点被经常用于桥梁桩基混凝土检测中。

With the rapid development of China’s economy, the operation of society and people’s daily life have been inseparable from logistics transportation. The rapid development of logistics and transportation industry benefits from the breakthroughs in road and bridge construction, so improving the quality of road and bridge engineering has a very critical impact on economic development. In bridge engineering, the pile foundation determines the stability, strength and durability of the bridge to a great extent. Therefore, the construction quality of pile foundation must be well grasped in bridge construction. In the detection methods of pile foundation concrete, there are mainly four methods: ultrasonic method, high strain dynamic method, low strain dynamic method and core drilling method. Among them, ultrasonic method is often used in the detection of bridge pile foundation concrete because of its comprehensive advantages and characteristics.
