摘要
新桥车场出入线位于重庆市沙坪坝区,属于重庆轨道交通九号线一期工程。文章结合钻孔取芯、地质测绘、室内及原位试验成果等数据,参考《铁路隧道设计规范》(TB 10003—2016),对工程区暗挖段洞室围岩分类进行研究,进行分段工程地质评价,针对主要工程地质问题提出合理化建议。
The access line of Xinqiao Depot is located in Shapingba District,Chongqing,which belongs to the first phase of Chongqing Rail Transit Line 9.Based on the data of drilling coring,geological surveying and mapping,laboratory and in-situ test results,and referring to the ’Code for Design of Railway Tunnels’(TB 10003—2016),the paper studies the classification of the surrounding rock of the underground excavation section of the engineering area is carried out,and the Section caverns have undergone a segmented engineering geological evaluation,and reasonable suggestions for major engineering geological issues have also been put forward.
