Twin Runway Integral Bridges at Milano Malpensa Airport, Italy

摘要

In this paper, two recently completed bridges at the Malpensa Airport have been presented. The bridges overpass the railway (which runs in a cutting, at a lower level) linking the Malpensa Airport to the city of Milan, Italy; and are part of a U-shaped path called the H (Hotel) Ring which connects the southern ends of the two existing taxi-ways. Such a crossing had to: (a) intersect the railway track twice with a skew angle of about 45°; (b) carry the maximum aeronautical loads, corresponding to the gears of an Airbus 380 aircraft and; (c) host a 60 m wide taxiway strip, plus a lateral safety lane and a service road, for a total width of 105 m. This paper briefly describes how the above requirements were dealt with while designing two integral bridges.
