Abstract
Early-built elevated metro stations often require expansion and renovation due to increasing passenger flow,while maintaining uninterrupted operation poses significant challenges.The core difficulties lie in construction organization and controlling differential settlement between new and existing structures.Taking the expansion pro-ject of Maqun Station on Nanjing Metro Line 2 as a case study,this paper presents practical solutions including op-timized zoned flow construction organization,three-dimensional simulation for settlement prediction,and dynamic monitoring with closed-loop control.These measures successfully achieved non-stop construction,ensured safety throughout the construction process,and maintained normal operation of the existing line.The station's newly added floor area reaches 7 735 m2,significantly enhancing its service capacity.The research outcomes are highly applicable engineering techniques that can be directly implemented in similar expansion and renovation projects of operating elevated metro stations.关键词
