摘要
隧道衬砌缺陷是影响公路交通安全通行的重要因素。探地雷达因其具有较强的抗干扰性、适应性强、分辨率高、操作简单、成果直观且为无损探测,而被广泛应用于工程勘察及地质调查中。为了进一步研究探地雷达作为一种快速、无损的检测方法在实际工程应用的有效性,该文基于电磁波基本理论和探地雷达基本原理,从山东在建某隧道衬砌缺陷检测的实际工程案例出发,通过分析检测结果中不密实、脱空、二衬厚度、钢筋分布等情况的图像特点,给出图像分析的精确方法,进而为探地雷达有效地应用于工程实际提供依据。
The tunnel lining defect is an important factor affecting the safety of road traffic.With the advantage of its strong anti-interference ability,strong adaptability,high resolution,simple operation,visually visible results and non-destructive detection,the ground-penetrating radar is widely used in engineering survey and geological survey.To further clarify the ground penetrating radar as a fast and non-destructive testing method,this paper presents an accurate method of ground penetrating radar on real engineering,from the example of the detection of lining defects in the slurry water spring tunnel,based on the theory of electromagnetic wave and the basic principle of ground penetrating radar,and the image characteristics of the void,the lining thickness and the distribution of the steel bars are also researched.The results will support the application of ground penetrating radar in real engineering.
