普通干线公路现役桥梁栏杆改造关键技术问题分析

Analysis on Key Technical Problems of Existing Bridge Railings Reconstruction of Common Trunk Highway

国省干线现役桥梁栏杆防护能力不足,亟需改造,系统分析总结了边梁承载力问题、混凝土护栏优化设计问题和翼缘板局部承载力问题,提出了相应的优化建议,为现役桥梁栏杆改造工程提供借鉴。

The protective capacity of the existing bridge railings of national and provincial trunk lines is insufficient and needs to be reconstructed.The bearing capacity of side beam,the optimization design of concrete guardrail and the local bearing capacity of flange plate are systematically analyzed and summarized,and the corresponding optimization suggestions are put forward,so as to provide reference for the reconstruction project of existing bridge railings.
