Power Tunnel Crossing Beijing Subway Line 1’s Wanshou Road Station

The project is a 110 kV power tunnel project from Zhengchangzhuang Thermal Power Plant to Balizhuang Substation. As a 3-meter-inner-diameter small shield tunnel, the power tunnel underpasses Subway Line 1’s Wanshou Road Station along the red line of the road in the west side of Wanshou Road. In the design phase, the route of Phase II of Line 10 also underpasses Line 1’s Wanshou Road Station, with a station at the intersection. In order to reserve spaces for the air duct and entrance-exit stru...

South-to-North Water Diversion Project’s Main Canal Runs beneath Beijing Subway Line 1’s Wukesong Station

The project is China’s first heavy-caliber urban rail transit line crossed by pressurized water-transmission pipelines. A 4-meter diameter double-track buried culvert is used to vertically underpass the subway station. The buried culvert is set 3.7 meters below the subway station. In combination with water-saturated sandy cobble stratum where the buried culvert crosses, the design adopts a long-pipe-grouting reinforcement scheme to ensure that the settlement deformation remains within 5 millime...

Underpass Project of Subway Line 13’s Beiyuan-West Wangjing Section on East Beiyuan Road

East Beiyuan Road starts from No. 3 Beiyuan Road in the south and ends at Binhe Road in the south of Qinghe River in the north. In the short-term plan, it is a secondary urban trunk road, and in the long-term plan, it is upgraded to an urban trunk road. It underpasses Subway Line 13’s Beiyuan-West Wangjing section in the form of a “10 meters-12.5 meters-12.5 meters-10 meters” four hole-box-culvert structure.
While ensuring subway operation, the project successfully implements the re-connec...

Beijing Subway Line 3 Phase-I Project Crosses Contract Section 01 of Existing Lines

The project starts from Dongsishitiao in the west and ends at Dongba in Chaoyang District, with a total length of 22.0 kilometers (all underground). There are 15 stations and 8 transfer stations, with an average distance of 1.46 kilometers. Dongba depot is set at the east end. The newly-built Line 3’s Phase-I project transfers with three existing lines. In the construction, transfer stations and their adjacent running tunnels have an impact on the existing stations and running tunnels to varyin...

Safety Impact Assessment on Existing Subway Lines Crossed by Beijing Subway Line 16

The project starts from Yongfeng of Beiqing Road in the north, and ends at Wanping, Fengtai District, with a total length of about 40.2 kilometers (all underground). Totally, there are 24 stations. The newly-built Line 16 successively passes the existing Line 4, Line 10, Line 6, Line 1, Line 7 and Line 9. Among them, there are 12 crossing stations, 3 in Line 4, 1 in Line 6, 1 in Line 7, 4 in Line 9, 2 in Line 10, and 1 in Line 1.

Safety Assessment on nearby Existing Lines Crossed by Beijing Subway Line 12

The project has a total length of about 29.3 kilometers (all underground). Totally, there are 21 stations, including 14 transfer stations (transferring with 13 lines). The newly-built Line 12 transfers with 13 existing lines. In the construction, transfer stations and their nearby running tunnels have an impact on the existing stations and running tunnels to varying degrees. To ensure the safe operation of the existing stations and running tunnels, a safety assessment was conducted on the existin...
