Abstract In the construction of tunnels under existing stations, it is necessary to control their settlement. When there a pile foundation in station, cutting has significant impact on settlement station. To determine influence piles subway reasonable pile-cutting time proposed. Based Chengdu Metro Line 9 underpassing 1 hatchery law tunnel station analysed via numerical simulation. Furthermore, deformation and stress characteristics piles, pipe roofs, linings supporting effect are discussed....

Settlement control of existing stations has consistently been a key issue in tunnel construction. Intermediate soil significant influence on the settlement station as connector between new and which should be considered when selecting measures. To clarify relationship state intermediate measures station, this study investigated 49 projects under elucidated soil. The failure was further analyzed by numerical simulation. Lastly, simple mechanical model constructed to determine stress...
When constructing open excavation and adding stories on the upper part of an existing station structure, new foundation pit contacts with at zero distance; subsequently, construction has a greater impact than that other close constructions. To explore cross-impact structures story-adding above station, in this study, through numerical simulation field measurement, we analyze deformation law retaining structure station. The following conclusions are obtained. leads to overall uplift sidewall...
