摘　　要：由于各种因素影响,国内大多数隧道衬砌都存在着不同程度的病害,诸如衬砌不密实、含有空洞、钢筋保护层厚度不足、钢筋外露等。其中,衬砌病害是隧道最常见的病害类型,对隧道结构稳定有重要的影响。考虑到实际工程中影响隧道衬砌结构稳定性的因素,利用地质雷达对隧道衬砌进行检测,对检测数据进行分析和高质量解译,并采集数据中的其他影响因素。通过提高隧道衬砌厚度和隧道衬砌缺陷的检测精度,准确定位隧道衬砌缺陷位置。Due to various factors,most tunnel linings in China suffer from varying degrees of diseases,such as incomplete lining,voids,insufficient thickness of steel reinforcement protective layer,and exposed steel reinforcement.Among them,lining disease is the most common type of tunnel disease,which has a significant impact on the stability of the tunnel structure.Considering the factors that affect the stability of the tunnel lining structure in practical engineering,the geological radar is used to detect the tunnel lining,analyze and interpret the detection data with high quality,and collect other influencing factors from the data.By improving the thickness of tunnel lining and the detection accuracy on the tunnel lining defects,the tunnel lining defects are accurately located.
