Optimization of the Construction Scheme for a PBA Metro Station Adjacent to an Existing Metro Tunnel北大核心CSCD

The Olympic Park Station crossing the existing Datun-Road tunnel covers a long distance and closely approaches an existing metro tunnel. Initially, the PBA construction method was adopted with eight pilot tunnels. In light of the tunnel group cavern effect and the surrounding soft silty clay with abundant water, the construction risks were very. Optimization of the metro station construction scheme was conducted, and the four pilot tunnels at the downside were cancelled and replaced with long drill hole grouting piles. Construction technology for a large-diame-ter pile for a bored pilot tunnel was adopted based on the engineering characters of the PBA method using four pilot tunnels. Monitoring on the Datunlu tunnel structure was performed during metro station construction and the results indicate that the construction scheme for the station’s main structure was rational; the new construction technology ensures construction safety for the existing tunnel and metro structure. © 2018, Editorial Office of "Modern Tunnelling Technology".
