The requirements of the road transport facilities increased accordingly. Bridge is required of it as a hub linking the two sides or ordinary people transport facilities with changing times and also bee more and more. China now has about 500,00 bridges in many kinds, and then more than 10,000 seats bridge had been start of construction in one year. Previously, China just a “Multibridge national” but now China just bee the “power of bridge country”. Bridges in the process of longterm use may produce different types of structural damage, some of these injuries, but also caused by natural disasters. With puters and the rapid development of science and technology, artificial intelligence will be widely used in various types of bridge structure testing and analysis. Meanwhile, interdisciplinary increasingly mon, some of the latest research results in hightech nondestructive testing technology research bridges, bridge inspection will promote the rapid development of technology. Thus came into being the bridge maintenance platform, bridge maintenance platform is used for maintenance of the bridge, and its quality is strictly necessary, and bridge maintenance platform by different anizations posed article focuses on bridge maintenance platform run institutions. Master Plan, part drawing, and then according to the the parameters using solidwords 3D mapping software run institutions through access to information to calculate the various parameters required by the design of bridge maintenance platform run institutions Key words: road; bridge; platform run institutions III 目 錄 摘 要 .................................................................................................................................................
