新建结构对已有轨道桥梁结构的影响因素分析

Analysis on Influencing Factors of Newly-built Structure on Existing Rail Bridge Structure

摘要:

轨道交通有着运力大、效率高、占地小及舒适性高等优点，在我国越来愈多的城市得到快速的发展。但是随着城市的进一步发展，新建市政设施或者工业、民用建筑难免对已建成的轨道交通结构造成影响。依托一座下穿轨道高架区间结构的新建桥梁，分析不同的基础形式对轨道高架结构的影响。

Abstract:

The rail traffic has the advantages of large transport capacity, high efficiency, small land and high comfort, and has been quickly developed in more and more cities of China. But with the further development of city, the newly-built municipal facilities or industrial and civil buildings inevitably have the impact on the built rail traffic structure. Relying on a new bridge underpassing the rail elevated section structure, the influences of the different foundation types on the rail elevated structure are analyzed.
