Abstract：
In light of the current inspection situation regarding the thickness and compactness of highway tunnel linings, the applicability and feasibility of various kinds of inspection methods are analyzed, and the basis of judgment for inspection results is determined. Such aspects as work platform improvement, measurement line layout and recording, constant dielectric calibration of the lining, inspection process records, result analysis, test reports and task implementation, which are involved in inspections by the geological radar method, are described. Some beneficial suggestions for future work are proposed.
