铁路装配式桥梁研究与应用综述

Review on Research and Application of Railway Fabricated Bridge

根据我国高质量发展的要求,建筑业要逐步实现绿色化、工业化、信息化、智能化,铁路桥梁装配化符合国家产业政策和可持续发展理念,是我国铁路桥梁发展的趋势和方向。我国铁路桥梁装配化起源很早,但发展缓慢,目前还处于试点应用阶段,没有形成完善的标准和技术体系。本文从梁部结构、桥墩、预制桩三个主要组成部分系统阐述了我国铁路桥梁装配化的试验研究和应用情况,根据目前我国铁路桥梁装配化的研究应用现状和主要存在的问题,提出了今后需重点解决的问题和主要研究方向。

According to the requirements of high-quality development in the new era of China,the construction industry should gradually realize green,industrialization,information and intelligence,and the assembly of railway bridges is in line with the national industrial policy and the concept of sustainable development,which is the trend and direction of the development of railway bridges in China.China’s railway bridge assembly origin is very early,but the development is slow,is still in the pilot application stage,has not formed a perfect standard and technical system.This paper systematically described the experimental research and application of railway bridge assembly in China from three main components:beam structure,bridge pier and precast pile.According to the current research and application status of railway bridge assembly in China and the main problems,the key problems to be solved and the main research direction are put forward.
