Paper Title:
Increase the Accuracy of GPR in Tunnel Detection
  Abstract

All aspects of measured process should be considered to minimize the negative influence then improve the GPR detection accuracy in the tunnel lining inspection. Take ChangBanPo tunnel test for example, in the case of not using measuring wheel, reducing the interpolation space improves accuracy of test data in the axial direction, and finally the positioning accuracy of the data is over 0.1m. By calculating the electromagnetic wave velocity of the end of the lining where the thickness is known, the velocity is used as the corresponding section of the lining ,which avoids the computational error by using dielectric constant and the error is controlled under the centimeter level.
