Abstract: Objective: Coordinating the interactive relation between URT (urban rail transit) systems and municipal pipeline networks in the underground space of roads to achieve safe, economic, and efficient development for both presents a major challenge in engineering construction. Therefore, conducting research on synergy of the coordinated construction of the two systems is of great significance. Method: Starting from the perspective of URT system construction and in combination with the needs for quality improvement of municipal pipeline networks, case analysis method is adopted to analyze the synergy between the two systems in three different scenarios: newlybuilt urban areas, established areas, and existing line renovation, providing solutions and methods to resolve possible conflicts in time and space. Result & Conclusion: In newlybuilt urban areas, the comprehensive utility tunnel with the reserved space for rail transit should be used to control and reasonably utilize the underground space. For the new URT line construction in established areas, a backbone municipal or nodal utility tunnel should be built along with the rail transit system, coordinating traffic guidance for stations, pipeline relocations, and planned municipal demands. In the context of urban renewal, the upgrading of municipal pipeline networks can be carried out in parallel with the renovation of existing URT lines, and small utility tunnels can be used as a means of space substitution.
