摘要
道床板隆起会直接影响列车的运行安全,一旦发生应迅速处理.本文针对贵州轨道交通1号线雅关隧道道床板隆起情况,对现场进行了轨道高差量测和取芯分析,结合水文地质情况、现场施工情况对隆起原因进行了分析,并提出了相应的处理措施,包括拱脚泄水、仰拱和道床板注浆加固、道床板植筋等.
The uplift of track bed slab can directly affect the safety of trains’operating,SO measures should be taken promptly once it takes place.In this paper,combined with the uplift condition of track bed slab in Yaguan Tunnel of Guiyang Metro Line 1,elevation difference survey and coring analysis were earned out.The reasons for the uplift were analyzed in view of the hydrogeological conditions and site construction,and corresponding countermeasures were presented,including water releasing in arch sluicing,grouting reinforcement of the inverted arch and roadbed slab,and inserting reinforced bars in track bed slab.
