摘要
研究了护栏不同状态(是否连接护栏板、与护栏板的相对连接位置、是否安装柱帽等)对半埋地立柱埋深的弹性波检测方法的影响,初步分析了不同状态下检测频率的变化、对测量结果的影响和处理方式,通过实验得出各状态因素的影响校正因子范围,为护栏立柱埋深无损检测中遇到的难题提供了一种解决途径,校正因子的精确值还有待于进一步研究验证。
The different conditions of guardrail and the influences of detection methods of barrier post embedded Depth in soil based on elastic wave method were studied. Such as whether or not to connect barrier plate and Install rubber cap, the relative position between guardrail and post etc. The change of detection frequencies, the influence of the detection results and the mode of processing were analyzed preliminarily on different states. The range of correction factors were obtained in various states by experiments, it provided a way to solve the problem that we met various difficulties in NDT for the embedded depth of post. It remained to be further verified the accurate value of correction factor through the experiment.
