| Abstract: | The Yarlung Zangbo River No. 3 Bridge is a super major bridge on Lhasa-Xigaze Railway,and the main bridge is with a span arrangement of( 88+148+880)-meter and with the characteristics of high structure and large span. A detailed comparison and selection,as well as calculation and analysis in relation to structure design of this bridge were carried out. Especially,in light of the characteristics of high earthquake intensity in the bridge site,the ideas of seismic isolation and shock absorption were put to good use in structure design of this bridge. |
