Abstract: In response to the problems of complex construction plans, low processing efficiency of applying for start and end construction, cumbersome planning, and interference from uncertain factors in the construction of urban rail transit operation lines, this paper designed an intelligent construction management system for urban rail transit operation line, elaborated on its overall architecture, functional design, and key technologies, and implimented functions such as construction plan management, construction operation control, and construction statistical analysis. The results of its operation on the Zhengzhou Metro show that the system can effectively reduce operating costs, improve construction management efficiency, and provide strong support for the management of urban rail operation lines and engineering construction.
