摘　　要：高速铁路系杆拱桥结构复杂,对变形控制要求高,其检查项目多,然而天窗点少且多在凌晨,检查养护非常困难。以武广铁路客运专线梁家湾大桥为工程背景,结合系杆拱桥特点,搭建系杆拱桥BIM模型,实现结构信息的可视化。在BIM模型的基础上,建立大桥运营监测系统平台,达到快速准确地了解桥梁实际运营状态的目的。采用MIDAS/Civil建立大桥有限元模型,并依据TB 10621-2014《高速铁路设计规范》和铁运函〔2004〕120号《铁路桥梁检定规范》确定重点监测内容,为今后的监测项目实施提供依据。The tied arch bridge of high speed railway has complex structure,high requirements for deformation control and many inspection items. However,it is very difficult to inspect and maintain due to few skylights and early morning hours. Taking Liangjiawan bridge on Wuhan-Guangzhou railway as the background,combining with the characteristics of tied arch bridge,a BIM model of tied arch bridge was established to realize visualization of structural information. Based on the BIM model,a bridge operation monitoring system platform was established to achieve the purpose of quickly and accurately understanding the actual operation state of the bridge. The finite element model of the bridge was established by MIDAS/Civil,and the key monitoring contents were determined according to TB 10621-2014 Design Code for High Speed Railway and the Letters of Railway Transportation〔2004〕No. 120 Code for Rating Existing Railway Bridges,which provides the basis for the implementation of monitoring project in the future.
