摘要
桩基在施工过程中易出现断裂、缩颈、扩颈、离析等质量问题,低应变反射波法是近年来应用比较广泛的无损测桩技术。文章介绍了低应变反射波法的基本原理,结合工程实例,对低应变反射波法用于桩基检测进行了探讨。
The problems such as fracture, reducing, increasing and segregation would easily occur in the construction of the pile foundation; low-strain reflection survey is a kind of nondestructive examination method commonly used in recent years. This paper introduces the fundamental principle of this method and combining with a project practice approaches the application of low-strain reflection survey to pile examination.
