【正文】 ly 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 .................................................................................................................................................
