摘要
青岛地铁M4号线里程CK0+000.0~CK0+889.1(m)段位于青岛前海滨海地段,线路穿越历史风貌旅游区及热点学区,周边环境与工程地质条件十分复杂,隧道结构紧邻海岸线,涉及明挖法、矿山法、TBM法等多种施工方法,施工安全风险高。在开展详尽岩土工程勘察工作的基础上,分析了该地段的地质构造、工程地质与水文地质特征;根据影响该段隧道施工的安全因素,指出了施工过程中可能出现的岩土工程问题;基于不同工法与隧道围岩分级特性,提出了针对性的设计与专项施工建议。研究成果对于青岛地区后续地铁线路的勘察、设计以及施工具有一定的指导意义。
Mileage CK0+000.0 ~ CK0+889.1(m) section of Qingdao metro line M4 is located in coastal zone,which cross historical landscape tourism area and hot school district. Owing to its special geographical location close to coastline and complex engineering geology and environment conditions,subway construction including subsurface excavation method,mine tunneling method and TBM method are confronted with hidden danger.On basis of geotechnical engineering investigation work results,geological structure,engineering geology and hydrogeology are studied. According to influencing factors of tunnel construction safety,the probable geotechnical problems during construction period are pointed out. Specific suggestion for design and construction are proposed based on different construction methods and rock mass levels. Achieved results can be served as a reference for investigation,design and construction of future metro lines in Qingdao area.
