摘要
漠阳江特大桥134m钢桁梁是目前国内铁路跨径最大的双线有砟简支钢桁梁,由于跨径较大,且漠阳江为四级航道,使用步履式顶推施工工艺避免了航道对施工的影响,且拼装场地较为固定,提高了设备利用率,缩短了工期,提高了施工安全系数。
The 134m steel truss beam of Moyang River Bridge is the largest double-track ballastless simply supported steel truss beam with the largest railway span in China.Due to the large span and the fourth-stage waterway of Moyang River,the influence of the waterway on the construction is avoided using the stepping jacking construction technology.And the assembling site is relatively fixed,which improves the utilization rate of equipment,shortens the construction period and improves the construction safety factor.
