ABSTRACT

In order to detect the width, depth of the tunnel lining crack and the depth and range of the empty ring, and analyze the tunnel lining strength in the disease area to ensure the quality of the project. Firstly, ultrasonic and geological radar are used for scanning, and the scanning image is analyzed, so as to determine the width, depth, depth and range of the tunnel lining crack. Finally, the test results show that the ultrasonic and geological radar inversion analysis of the width and the depth of the tunnel lining crack first group are 3.14mm and 91.1mm respectively, the second group is 3.17mm, 75.8mm respectively, the length of the first group of core sampling is 90.0mm, the second group is 75mm, the error rate is 1.05%~1.2%, high confidence. The minimum strength of point load test concrete is 44.32 MPa, the maximum value is 53.48583 MPa, and the average value is 48.4 MPa, which meets the requirements of lining strength C35 concrete.
