Alignment Design of Urban Railway Station Bridge - Huaqiao Bridge Section Reconstruction Project in Qimen County

摘要:

随着经济社会的发展，越来越多的山区小城对外交通通道进行改造，对于近城段的公路，不仅具有公路属性，在一定程度上也具有城市道路的功能，合理调整路基断面型式，服务于近城段多样性交通型式。根据V字河谷地形的特殊性，在布线中处理好与河道、铁路的关系，便于项目实施。

Abstract:

With the development of economy and society, the external traffic channels are reconstructed in more and more small mountain towns. The highways near a city have not only the highway property, but also the urban road functions to some extent. The subgrade section type is reasonably adjusted to serve the diversity of traffic patterns near the city. Based on the particularity of V-shaped valley topography, the relationship with the rivers and railways should be handled properly in the alignment layout, which is convenient to the project implementation.
