摘要
在既有建筑物下方的软弱围岩中进行浅埋暗挖城市地铁隧道施工,开挖方法和超前支护方法的优选对保证建筑物的正常使用和安全是非常重要的。本文结合深圳地铁4号线下穿莲花北路浅埋暗挖的工程实例,探讨了CRD法结合大管棚和小导管超前预支护技术在地铁中的应用。
The optimization of construction and advanced shoring method is extremely important for the tunneling construction of urban subway under existing buildings on soft rock foundation to ensure the normal use and safety. This paper taking North road of Xiachuanlian of No. 4 line of Shenzhen subway as an example, discusses the application of CRD combined with big pipe shed and ductile shoring technique in subway.
