巴伦台至伊尔根地方铁路保然特大桥主桥设计

Main Bridge Designing of BaoRan Bridge from BaLunTai to YiErGen Railway Station

以实际工程为背景,介绍了集高墩、大跨、小曲线半径、严寒、高烈度地震及高风压于一体的铁路连续刚构桥梁受力特点。对其上、下部结构尺寸的拟定及设计进行了研究,介绍了桥梁结构尺寸与技术关键点,使用MIDAS/Civil分析软件对其支反力、刚度、自振频率与抗震进行了分析,并对关键的施工措施进行了简单的阐述。

Based on real project,force-bearing characteristics of continuous rigid frame bridge with high pier,large span and small curve radius in cold areas with high intensity earthquake zone and high wind pressure is described.The structural dimensions and designs are researched.The structural dimensions and the main technical key points are described.The reaction forces,stiffness,natural frequency and earthquake effect are calculated using MIDAS/Civil structural analysis software,and crucial construction measures are elaborated.
