【摘要】 使用荷载—结构模式进行隧道衬砌可靠度分析时 ,一般用弹性支承链杆来代替围岩与隧道衬砌结构的共同作用。对单线电气化铁路隧道衬砌标准设计图按相同设计参数 ,但将弹性支承链杆分别按水平和法线方向进行可靠度分析比较 ,其结果说明弹性抗力方向对隧道衬砌可靠度有显著的影响更多还原

【Abstract】 Normally, in the reliability analysis of tunnel lining struction according to the load structure model, the elastic supporting rod is used to imitate the mutual effect between surrounding rock and tunnel lining structure Supposing the elastic reaction to be in horizontal and normal direction, respectively, the reliability of standard single track electrification railway tunnel lining is analysed with same design parameters Comparison of the calculation results shows that the effect of elastic reaction direction is substantial on tunnel lining reliability更多还原
