高速公路桥式设计与选型

Expressway Bridge Design and Type Selection

高速公路桥式设计与选型除满足设计要求、工程投资、桥址工程条件外,还需考虑桥梁与周围环境的协调统一、桥梁各部件间比例与尺度的匀称均衡。由于高速公路一般为长大干线,从简化设计与方便施工角度考虑,其桥式的设计与选型通常采用部颁标准图。通过对高速公路桥式设计与选型的定性分析,揭示了一般规律及常用的方法。

Expressway bridge design and type selection should not only meet the design requirements, project investment, preliminary engineering conditions, but also take account of the harmony and unitarity of bridge and the surrounding envi- ronment, and proportion and scale of symmetrical balance between the components of bridge. Since expressway is usually the long distance line, from the perspective of simplified design and convenient construction, the bridge type design and se- lection usually adopt the ministerial standard drawing. Based on the qualitative analysis of expressway bridge type design and selection, proclaims the general rule and the commonly used methods.
