摘要
青岛地铁1号线下穿白沙河北段,将采用盾构法施工,洞身穿越主要地层为含卵碎石粗砾砂层.以隧道穿越地层专项勘察为切入点,对其工程地质特征进行详细阐述,并针对下穿地层对盾构法施工应注意的隧道施工安全问题进行分析与评价,提出了相应的建议,为后续盾构设计选型、施工提供可靠依据.对青岛地区地铁线路勘察、设计以及施工等具有一定的借鉴及指导意义.
The construction of the north Baishahe section of Qingdao Metro Line 1 takes the shield method to make a tunnel through the main formation of eggs gravel coarse in sand gravel layer. With the formation of special investigation as the breakthrough point, the pa-per takes aim at the wear formation of shield construction, states the engineering geological characteristics, and puts forward the corresponding suggestions for the subsequent shield de-sign selection and the construction. In Qingdao area, every subway line in survey, the design and construction has a certain reference and guidance significance.
