跨某高速公路钢箱混凝土门式墩设计

The design of reinforced concrete portal pier over some express highway

结合工程实例,介绍了高速公路钢箱混凝土门式墩的结构设计与施工,对墩柱承载能力及柱脚需要螺栓数量进行了计算,根据该桥墩的特点,提出了合理的防腐设计方案,从而减少对现有道路交通的影响。

Combined with the specific engineering examples, the structural design and construction of reinforced concrete portal pier over express highway were introduced. The bearing capacity of pier and bolt quantities required in pier foot were calculated, according to the pier characteristics, the proper anticorrosive design planning was proposed so as to decrease its influencing on the existing road traffic.
