摘要
重载运输独有的大轴重、高密度、长编组的运输模式给铁路运输业带来巨大效益,但也不可避免的会导致涵洞病害大量出现并迅速发展,致使其结构承载能力下降。以朔黄铁路低填土盖板涵洞为研究对象,针对其板梁横向联结失效,单板受力问题突出这一病害,开展了低填土盖板涵加固及受力性能分析,并与试验实测数据进行了对比分析。
With the vigorous development of railway transportation industry,the unique transportation mode of heavy haul transportation with large axle load,high density and long marshalling has brought great benefits to the railway transportation industry,but it will inevitably lead to the rapid development of a large number of culvert diseases,resulting in the decrease of structural bearing capacity and service performance.The safety problem of culvert operation under heavy haul transportation is becoming increasingly prominent.Taking the slab culvert with low fill cover of Shuohuang Railway as the research object,aiming at the failure of transverse connection of slab beam and the stress problem of single slab,the reinforcement and stress performance analysis of slab culvert with low fill cover are carried out,and the results are compared with the experimental data.
