Abstract EN
This paper presents a case of subway station construction under an existing prestressed concrete bridge with a three-span continuous beam located at the intersection of the 3rd Ring Road, Beijing.
The Huayuan Subway Station of line 6, constructed crossing between #7 and the #8 piers of the bridge by the shallow tunneling method, is approximately perpendicular to the existing Huayuan Bridge.
The minimum horizontal distance between the pile foundation and the subway station is only 0.08 m.
The “Pile-Beam-Arc” construction sequence was used to ensure the safety of both the subway station and the bridge.
Moreover, a series of reinforcement measures were adopted to safeguard the project, including deep grouting reinforcement surrounding the pile foundation from ground surface, temporary inverted arch in the middle of No.
5 drift, and the lateral steel support.
Even though some cracks were observed on the bridge deck surface by the on-site deformation monitoring, the results were still within the proposed control standard.
To prevent the further development of the cracks, jacking protection measure and bonded steel constructed under the box girder were performed.
The related measures proposed in this research can provide useful references for future similar projects.
