Abstract
The Nianchu River Bridge,a super major bridge with a novel style structure,perches on the Lhasa-Shigatse Railway.Its main bridge is made up of a hybrid structure of V-shaped rigid frame plus concrete-filled steel tube arch with a span arrangement of (60+148+60) meters.The paper elaborates the design features of this bridge type,carrying out static and dynamic analysis for the main bridge,and calculating the load capacity,seismic resistance,vehicle-bridge dynamic response and other structural factors in detail.This bridge is an organic integration of V-shaped continuous rigid frame with concrete-filled steel tube arch,making full use of the advantages on structural behaviors of both the V-shaped rigid frame and the arch.Thus this bridge not only can meet the requirements on safety and on riding comfort of the train,but can be harmonious with the natural landscape around as well.关键词
