[HTT18-01] Improving the efficiency of under-road cavity investigation using on-vehicle Ground-Penetrating Radar
Keywords:under-road cavity investigation, vehicle-mounted 3D Graund-Penetrating Radar, AI analysis software, road cave in, infrastructure maintenance management
In recent years, roads have been damaged by localized torrential rains, earthquakes, and the effects of tunnel propulsion work, and the number of cases covered by the media has increased. There is also an increasing number of cases where cavities occur under roads due to damaged underground structures such as sewage pipes, leading to accidents where the road cave in.
For this reason, under-road cavity surveys are frequently carried out every year at the request of the Ministry of Land, Infrastructure, Transport and Tourism and local governments. These surveys require collecting data from tens to hundreds of kilometers within a limited period and analyzing it to identify anomalies that are suspected to be cavities.
In order to solve the above-mentioned issues, the measurement work was carried out using a vehicle-mounted 3D Ground-Penetrating Radar that does not involve traffic regulation, and the analysis work was automatically performed using AI analysis software developed in-house. These efforts have made it possible to significantly shorten the number of days required for measurement and analysis, making the investigation more efficient.
