摘要
以青岛地铁1号线汽车北站到流亭机场站盾构区间施工为例,由于该段穿越了软弱砂层并下穿建筑物,使得施工面临着诸多问题,用数值模拟的方式分析了其具体的施工过程,有助于提高施工质量。
Taking the construction of the shield section of the North Bus Station of Qingdao Metro Line 1 to the Liuting Airport Station as an example,the construction faces many problems because it crosses the weak sand layer and passes through the building,using numerical simulation.The concrete construction process is analyzed to help improve the construction quality.
