摘要
为确保大跨度明挖隧道结构施工安全、高效,通过对隧道拱架的设计及验算,满足现浇钢筋混凝土结构支架强度、刚度、稳定性的要求,同时可实现拱架厂内预制,施工现场快速安装、使用安全、安装过程质量易控制等,并提出相应的措施建议。对于类似工程具有推广应用价值。
In order to ensure the construction safety and efficiency of large-span open-cut tunnel structure,through the design and check-ing calculation of tunnel arch,meet the requirements of strength,stiffness and stability of cast-in-place reinforced concrete structure support,and can realize the precast of arch in the factory,quick installation on the construction site,safe use,easy quality control in the installation process,and put forward the corresponding measures and suggestions.It has the value of popularization and application for similar projects.
