도심 터널구조물 외관 비파괴 검출 시스템 = Exterior Detecting System for NDT of Tunnel Structures in the Metropolitan

다국어 초록 (Multilingual Abstract)

Passenger's tunnels for trains, cars and metro as well as utility tunnels have seen their numbers soared. Recently, the tunnel structures are increasing. And the tunnels are to be large diameter tunnel and long. Therefore, inspection, repair, and maintenance of tunnels are an extrernely important part of infrastructure management, with particular technical and safety considerations arising from the very nature of underground construction. To inspect surface state of tunnels, concrete structures, it must generally use method of conventional visual inspection, but this method is very not objective. To measure the width, length, position, direction of a crack, it is very difficult, when the tunnel is long span and high rise. Thus, to make up for this demerits, in this paper is proposed the system that we can check conditions of the tunnel structures quickly, detect the detailed data objectively, count automatically, the width of a crack by the original software and follow the trend of long term changes in the condition of a structure.
