摘要
随着城市的不断发展,地下空间的开发成为城市交通的重中之重。但是,在盾构施工中遇到不良地质,不仅会增加施工难度和风险,也会影响施工进度,对特殊地层的处理至关重要。以济南市某区间的地铁隧道施工为例,介绍通过置换法改变地质来处理孤石的方法,为今后的类似施工工况提供参考。
With the continuous development of the city,the development of underground space has become the most important part of urban traffic.But in the shield construction,the bad geology will not only increase the construction difficulty and risk,but also affect the construction progress,so it is very important to deal with the special stratum.Taking the subway tunnel construction in an area of Jinan as an example,this paper introduces the method of dealing with boulder by changing the geology by replacement method,which provides reference for similar construction conditions in the future.
