摘要
以1座(70+120+70)m连续刚构桥为工程背景,分析设计过程中主墩关键参数,包含主墩墩高及桥墩形式、左右主墩高度不对称等对主梁及墩身关键截面内力、墩顶水平位移的影响规律,得出相关结论以指导连续刚构桥设计。
A（70＋120＋70）m continuous rigid frame bridge is taken as the engineering background,analysis of the key parameters of the main pier int the bridge design,including the height of the main pier and pier form,the height asymmetry of the two main pier,which influences the internal force of girder and pier key section as well as the horizontal displacement of pier top. The relevant conclusions are drawn to guide the design of continuous rigid frame bridge.
