摘要
介绍隧道支护原理及探地雷达探测原理,结合某公路隧道工程,分析探讨隧道无损检测的具体应用。介绍工程测线布置,从喷混厚度、拱架间距、喷混与围岩的接触情况分析初支检查结果;从空洞及不密实缺陷、钢筋数量及间距分析二衬检测结果。
This paper introduces the principle of tunnel support and ground penetrating radar detection.Combined with a highway tunnel project,the concrete application of tunnel nondestructive testing is analyzed and discussed.The layout of engineering survey line is introduced,and the initial inspection results are analyzed from the thickness of jet mixing,the spacing of arch frame and the contact between jet mixing and surrounding rock.The results were analyzed from the defects of voids and incompacts,the number and spacing of rebar.
