Abstract:The high-speed railway tunnel lining always suffers from some adverse conditions, such as thickness lack, cavity, and unreasonable reinforcement arrangement. In this paper, simulation of the typical adverse lining condition was introduced by using the simulation software GPRMax2D based on finite-different time-domain method (FDTD), and the forward simulation radar images of the typical adverse lining condition were obtained. In combination with the typical radar images from detection examples of a high-speed railway tunnel, a comparative analysis was made between them, the features and rules of the adverse lining condition were summarized, the ground-penetrating radar data feature library was improved, and the credibility of recognizing typical adverse conditions of high-speed railway tunnel was increased. These results provide the effective basis for the high-speed railway tunnel non-destructive testing.
