摘要
针对长沙轨道交通7号线铁道学院东站至雨花亭站区间隧道穿越复杂建筑群方案不清晰问题,在分析既有隧道实际状态的基础上,结合方案对比及数值仿真等研究,得到合理线路及施工方法,并提供了相关建议。研究认为,该区间隧道上跨长沙隧道,之后从桔园立交桥西侧绕行方案较为合理可行。明挖法上跨施工具有易处理地下障碍物、可实施性强等优点,且对长沙隧道变形影响处于可接受范围内,推荐其为本工程施工方案。研究成果可为新建地铁隧道穿越复杂建筑群线路及工法的拟定提供指导。
There is still unclear for the section tunnel of Changsha Subway Line 7 from Railway College East Station to Yuhuating Station about how to pass through the Changsha Tunnel of Beijing-Guangzhou Railway and Juyuan Interchange.By using methods such as scheme comparison and numerical simulation,the reasonable route and construction method for this section tunnel are determined according to the actual state analysis of the existing tunnel,and relevant suggestions are further provided.Research results suggest that it is more reasonable and feasible for this section tunnel to span the Changsha Tunnel and to detour from the west side of the Juyuan Interchange.The cut and cover method for span construction has the advantages of easily handling underground obstacles,strong feasibility,and an acceptable impact on the deformation of Changsha tunnel.Therefore,it is recommended as the construction plan for this project.The research results can guide the formulation of routes and construction methods for the construction of new subway tunnels crossing through complex existing building groups.
