摘要
介绍了目前高速公路护栏立柱埋深的检测方法以及该领域无损检测方法的研究进展。针对目前广泛使用的拔桩检测法的不足,在研究超声导波和弹性波传播特性的基础上,分析了基于这两种波的无损检测方法的原理、设备、特点及其在护栏立柱埋深检测方面的应用,指出开发应用简便、检测精度高的便携式无损检测设备是今后研究的方向。
The detection method of expressway guardrail post length embedded in soil was introduced.And application and research progress of non-destructive test methods used in the field were also studied.Aiming to the shortcomings of the pile method used widely at present,based on ultrasonic-guided wave and elastic-wave spreading characteristics,the testing principle,testing equipment,advantages and disadvantages,as well as the application of the two kinds of waves in the detection of post length embedded in soil were analyzed.The non-destructive testing device,which is accurate,easy to operate and portable,will be a developing trend of this field.
