Maintenance of today's bridge infrastructure presents many challenges. Transportation engineering and maintenance personnel must maintain around the clock service to millions of people each year while maintaining millions of cubic meters of concrete distributed throughout their facilities. This infrastructure includes bridges. Presently only a limited number of accurate and economical techniques exist to test these structures for integrity and safety as well as insure that they meet original design specifications. 〔 Weil, Gary J. “Nondestructive Testing of Large Concrete Structures.” SPIE 3397 (1998).〕 No single technology can locate all physical anomalies in and below the concrete, these techniques along with data fusion can assist in the following investigations, to name a few: #Locating voids and delaminations in bridge pavements and scour around bridge support columns. #Determining location and types of reinforcing steel in concrete #Ensuring quality control on new concrete installations == Techniques == 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bridge maintenance」の詳細全文を読む スポンサード リンク
