以新建的200km时速双层集装箱运输的赣州至韶关铁路单线隧道衬砌断面为研究对象，借助数值模拟手段，得到了围岩压力百分比、弹性反力系数、二次衬砌厚度、浅埋隧道覆土厚度和偏压隧道地面坡对隧道衬砌内力的影响规律，其结果可为今后200km时速的铁路隧道衬砌设计和优化提供参考。

 Taking the crosssection lining of 200km/h GanzhouShaoguan single track railway tunnel as research objective, the author introduces the influence rules of many factors on the internal force of tunnel lining by means of numerical simulation. These factors include surrounding rock pressure percentage, elastic reaction coefficient, secondary lining thickness, cover depth of shallow buried tunnel and surface gradient of asymmetricallyloaded tunnel. This paper can provide references for the design and optimization of 200km/h railway tunnel lining in the future.
