Project Description

Summary: Complete monitoring of new Arsta Railway Bridge

Clients: Bemek Geomekaniska Instrument AB

Place: Stockholm (Sweden)

Period: 2002 - 2003

Installation: Bemek AB / Smartec SA

Structure's short description: The Arsta railway Bridge is the new double-track Arsta railway bridge. The new bridge, will span Stockholm's Arstaviken bay, with a length of 833 meters / 2732 feet. The bridge will include service roads on each side of the tracks with pedestrian and bicycle paths.

Aim of monitoring: The aims are: The comparison of the monitoring results whis theoretical hypotheses Controll of the bridge behaviour during construction, testing period and life span Verify the uncertainties of bridge design, increase know-how for future projects integrating monitoring in bridge design

Number of sensor: 46

Main Results: The sensors installation will start next January 2003

New bridge next to old bridge. (it is possible to see concrete pillars and construction works at each river side)
