摘要
盾构法是一种常见的隧道掘进方法,但由于地质条件复杂,在盾构过程中,会出现掌子面不稳定等情况,存在坍塌的风险,因此需要采用超前注浆的方法,对掌子面和周围土体进行加固。以深圳地铁14号线某区间为例,研究超前注浆技术在地铁盾构施工中的应用,为以后类似工程提供方法和基础。
The shield method is a common tunneling method, but due to the complex geological conditions, in the process of shield tunneling, the face of the tunnel will be unstable, and there is a risk of collapse. The subsurface and surrounding soil are reinforced. Taking a section of Shenzhen Metro Line 14 as an example, this paper studies the application of advanced grouting technology in subway shield construction, which provides a method and basis for similar projects in the future.
