摘要
在铁路设计中,受既有道路及河流沟渠影响,不可避免地需要采用斜向布置的桥梁。刚构连续梁能够有效解决线路斜交问题。论文以时速160km单线铁路16m+2×24m+16m刚构连续梁为例,结合设计原则和主要技术参数,针对刚构连续梁的结构受力特点,利用MIDASCivil和桥梁工程师软件分别对桥梁上部结构、桥墩和基础分别进行计算分析,设计经济合理的主梁、刚壁墩及基础,总结出设计要点。
Affected by existing roads, rivers and ditches, it is inevitable to adopt the bridge with oblique arrangement in the railway design.Skew rigid-frame continuous beam can effectively solve the problem. This paper takes a single track railway with a speed of 160 km per hour16 m+2 ×24 m+16 m rigid frame continuous beam as an example, combined with the design principles and main technical parameters, and aiming at the structural stress characteristics of the rigid continuous beam, MIDAS Civil and bridge engineer software are used to calculate and analyze the bridge superstructure, pier and foundation respectively, to design economical and reasonable main beam, rigid wall pier and foundation, paper also summarizes the design points.
