摘要
在含大漂石的富水砂卵石地层采用盾构法施工在国内尚属首次,以成都地铁1号线盾构4标右线隧道泥水平衡盾构施工为例,结合施工中出现的问题,对泥水平衡盾构在砂卵石地层中的适应性进行初步研究,并提出相应的改进措施,对后续工程施工具有借鉴意义。
It is the first time in China to apply shield tunneling in the water-soaked cobble ground with large boulders. With the right tunnel of shield tender lot 4 on Chengdu metro Line 1 driven by slurry shield as an example and considering the problems encountered in the construction, this paper makes a tentative study on the adaptability of slurry shield to the watersoaked cobble ground with corresponding improvement measures put forward.
