Load-Bearing Structure
The load-bearing structure of the Ganter Bridge consists of a longitudinally and transversely prestressed jointless eight-span frame. The bridge girder is designed as a rectangular box girder without lateral brackets. The flanges of the two main piers P3 and P4 are raised laterally next to the bridge girder and serve as pylons for the four prestressed tension sheaves. Piers P2 to P7 are rigidly connected to the superstructure; only pier P1 and the two abutments have sliding bearings. Piers P1, P2 and P3 are restrained in the rock on the right side of the valley. The footings of piers P4, P5, P6, and P7 are sliding bearings to compensate for the creep of the left valley slope, and pier footing P4 is temporarily fixed (articulated).
Bearing:
- WL North:
- 2 sliding bearing Na / Nb (side Brig)
- 1 guided bearing Nc
- Pillar P1:
- 2 sliding bearing 1a / 1b
- 1 guided bearing 1c
- WL South:
- 2 sliding bearing Sa / Sb (side Simplon)
- 1 guided bearing Sc
- Pillar P4:
- 2 fixed bearings, PN 10.200 adjustable on sliding surface
- 2 longitudinal force bearings F 560
- 1 transverse force bearing F 780
- Pillar P5 / P6:
- 2 sliding bearings PNGA 2'400 and PNGA 2'900 on sliding surface adjustable
- 1 shear force bearing F 325
- Pillar P7:
- 2 sliding bearings 7a / 7b
Roadway expansion joints:
- WL North (Brig side): 2-section modular expansion joint
- WL South (Simplon side): 5-section modular expansion joint
- .
Prestressing systems:
- Longitudinal prestressing: cable with strands ø 0.50" (1'600/1'800 N/mm²), VSL system
- Cross prestressing: bar tendons (850/1'050 /mm²), Dywidag system
Sealing / surfacing:
PBD bituminous waterproofing membrane / base course HMT 16 N as well as top course AB 11 N
Special equipment:
- Lighting: along the entire length of the box girder
- Safety barriers: guide wall in solid reinforced concrete with lateral guardrail profile A and IPE posts with box section 150 / 180 placed on top of the wall crown.
Anchorages:
- Rock anchorages piers P2 / P3: cable with strands ø 6" (1'600 / 1'800 N/mm²) system Freyssinet
