高墩大跨曲线连续刚构桥的概念设计

Conceptual Design of High-pier Long-span Curved Continuous Rigid-frame Bridge

为研究高墩大跨连续刚构桥的概念设计,基于实际设计项目,综合考虑桥梁的高墩、大跨、曲线桥特点和桥位处的强地震、高风速、严寒区等自然环境因素,从选线、桥型、景观、跨径、尺寸、刚度、稳定、抗震、施工、造价、材料和结构验算等角度出发,分析总结了高墩大跨连续刚构桥的设计思路及注意事项,从而为同类桥梁设计提供参考方法。

In order to study the conceptual design of a high-pier long-span continuous rigid-frame bridge,based on an actual design project,the characteristics of high pier,long span and curved bridge,and the natural environmental factors of strong earthquakes,high wind speeds and severe cold areas at the bridge location are comprehensively considered,starting from the perspectives of route selection,bridge type,landscape,span,size,stiffness,stability,earthquake resistance,construction,cost,material and structure check,the design ideas and precautions of the high-pier long-span continuous rigid-frame bridge are analyzed and summarized so as to provide a reference method for the design of similar bridges.
