采用钢板加固隧道二衬混凝土结构受力分析

摘要

According to the situation of insufficient thickness of a highway tunnel local section lining,using the bonding steel plate made rein-forcement structure,through the force analysis on steel reinforcement structure,pointed out that using the steel reinforcement and treatment of tunnel second lining insufficient concrete thickness could effectively improve the flexural bearing capacity of second lining concrete.%针对某公路隧道局部段落衬砌厚度不足的情况，采用粘贴钢板法进行结构加固，通过对钢板加固结构的受力分析，指出运用钢板加固处治隧道二衬混凝土厚度不足可有效提高二衬混凝土抗弯承载力。
