Tunnel accident is apt to become a serious disaster when it occurs. But tunnel construction is being increased rapidly in Korea because tunnel has advantages and usefulness. According to Korean Ministry of Land, Transport and Maritime Affairs, total length of road tunnels was extended from 150 km to 648 km for last decade (333% increased). On the other hand there are several tunnels aged about 100 years. Therefore systematic health monitoring is necessary to these old and new tunnels during their life time. But conventional tunnel management systems in Korea have several limitations. First, they were made for each tunnel on a case by case and not integrated totally. Second, they are uncomfortable to use because they used wire based sensors and non-graphic user interface. So we developed integrated tunnel monitoring system using wireless and automated data collection, 3D CAD system. We used system modularization technology to integrate and apply various tunnels, Zigbee technology to collect data and Korean 3D technology to display sensing values. This paper describes framework and prototype of this system.
