  • To ensure safety and stability of the reconstruction and expansion of the newly built station under a nearly 50 years long-term service station, the structural status of main structure and auxiliary structure of an operating station and a reserved station is inspected. The construction deformation control standard is formulated referring to the structural state. The construction impacts of different expansion construction schemes are compared by using numerical simulation. Then the effect of an optimized scheme is verified in combination with an on-site implementation. The results show that there is a series of problems in the early-built station structure, such as decoration layer falling, concrete cracking, spalling, carbonization, steel corrosion, floor leakage, interval water accumulation and uneven settlement of deformation joints. For the CRD (central cross diagram) scheme, the maximum settlement of the reserved Line 3 station is 2.2 mm, and the surface settlement is 1.7 mm. For the PBA (pile beam arch) scheme, the maximum settlement of the station is 1.3 mm, and the surface settlement is 1.1 mm. The PBA method is recommended for the reconstruction and expansion project after a comprehensive consideration of various factors. After adopting the PBA construction scheme, the maximum vertical deformations of Line 2 and Line 3 structures are −1.28 and −1.01 mm, and the monitoring indicators are within the safety thresholds. The research results can provide a reference for similar subway station reconstruction and expansion projects.
