TBM通过软弱地层施工方法的探讨

Soft formation construction method discussion though TBM

通过引黄工程北干线1号隧洞工程实例,分析了TBM通过的软弱地层地质情况,对承包商提出的三种施工方案进行了介绍,比较了三种方案的优缺点,得出了第二种方案比较适合该工程的结论,可供同类工程借鉴。

Through the first tunnel project example in the Yellow river seepage project, it analyzes the geology condition of the soft formation passed by TBM, introduces the three construction schemes brought by contractor, compares the merits and faults of this three schemes, and gets the conclusion of the second scheme needing this project more, which will supply references to the similar projects.
