Abstract:   In the area of Wojanów railway tunnel (Sudetes Mts., Poland), Ground Penetratind Radar (GPR) was employed in the context of a geotechnical research for the purposes of designing the tunnel renovation. Various antennas were used, with 100 MHz, 250 MHz, and 800 MHz central frequencies. The sections recorded above the tunnel with 100 MHz antennas allowed estimating at what distance from the tunnel casing, behind the housing, there is a solid rock. The cross-sections recorded with 250 MHz antennas allowed figuring out the structure of the ground behind the tunnel casing. The analysis of data obtained with 800 MHz antennas made it possible to precisely determine the condition of the tunnel casing and of the casing reinforcement zone. An attempt was also made to analyse GPR data in a three-dimensional system, to study the general state of the ground behind the tunnel casing the analysis indicated loosening rocks and empty spaces behind the tunnel casing.

Keywords: Ground Penetrating Radar (GPR); Civil engineering; Railway tunnel.


Ground-penetrating radar (GPR) is a safe and valuable method for the non-destructive testing of transport infrastructures, including tunnels [1], [2]. In the scientific literature, several works address the successful use of GPR for the assessment of roads and bridges, whereas a rather limited number of case studies deal with the use of this technique for the investigation of tunnels [3]–[23]. This is probably due to the fact that tunnel inspections present considerable practical difficulties, compared to roads and bridges, therefore they are less frequent. The objectives of this paper are to present the results of a GPR survey carried out in Wojanów railway tunnel, in Poland, and to provide practical guidelines for GPR inspection of tunnels.
