Abstract
As the leading corridor and construction space of the Beijing-Shenyang dedicated passenger railway line leading into Shenyang railway junction is very narrow, the project needs to cross over Qinhuangdao-Shenyang dedicated passenger railway line, several normal speed railway lines, rivers, municipal roads and pipe lines. The precise, scientific and reasonable transition and protection design of bridge project leading Beijing-Shenyang dedicated passenger railway line into Shenyang railway junction has solved such problems as follows: so many special bridge structures, complicated transition options and construction difficulties;challenges in the protection of adjacent existing facilities, traffic organization in upgrading rail/road overpass;so many sensitive points, strict elevation requirement and interference;high standard of automatic subsidence and deformation monitoring required by Qinhuangdao-Shenyang dedicated passenger line and other difficulties. The design ensures normal operation and safety of the existing equipment and is proved reasonable and economical for bridge transition and protection and makes it possible to allow Beijing-Shenyang high-speed railway to be introduced successfully into Shenyang railway junction in such a small space.关键词
