摘要
以贵州省瓮安河特大桥主桥设计为背景,介绍了高矮墩大跨连续刚构桥主墩的等刚度设计,结果表明,该桥主墩墩身承载力、稳定性、裂缝宽度、抗震性能均满足规范要求,以期对同类桥梁设计及研究提供参考。
Taking the design of main bridge for Weng 'an Grand Bridge in Guizhou province as the background,the design of equal rigidity of main pier for large-span continuous rigid frame bridge with tall-short pier is introduced. The results show that,the bearing capacity,stability,crack width,and anti-seismic property of the main pier body of the bridge meet the requirements of standard,so as to provide reference for the design and research of the same type of bridge.
