【摘要】 南京市龙潭港疏港一级公路在栖霞山铁路隧道北侧呈近距离平行延伸 ,挖方路基距离铁路隧道的最小净距仅为 11.9m ,按相关规范推算现有铁路隧道宽 9m ,高 8.5 m。为了确保施工期间沪宁铁路栖霞山隧道的正常运营 ,必须对设计路线给予正确合理的分析评估 ,以保证设计方案合理、参数取舍可行 ,最终对路堑的施工方法、施工方案提出了工程预防措施更多还原

【Abstract】 The diversion highway of Dragon Port in Nanjing City is situated in the northern side of Xixiashan Railway Tunnel, the nearest net distance between the through cutting boundary and railway tunnel is 11.9 meters,and the railway tunnel is 9 m in width and 8.5m in height?In order to warranty the normal operation of railway, a series of related parameters of highway including construction scheme and construction method are analyzed by two dimension elastic-plastic FEM code, finally, some conclusions and suggestions about highway design and the excavation scheme of the through cut are presented.更多还原
