基于 FTGS 轨道电路限制下的地铁整体道床配筋设计

摘要

From the structure force,drainage demands,durability aspects,this paper analyzed the necessity of arrangement double layers rein-forcement of monolithic track bed,and put forward the upper layer glass fiber reinforcement( GFRP)+ lower layer reinforced composite double reinforcement arrangement was the optimal scheme of track bed reinforcement layout under the influence of FTGS track circuit signal system.%从结构受力、排流需要、耐久性方面入手，分析了整体道床应布置双层钢筋的必要性，同时提出了上层玻璃纤维增强筋（ GFRP）+下层钢筋复合双层钢筋布置是FTGS轨道电路信号系统影响下道床钢筋布置的较优方案。
