摘要
地铁隧道常修建在城市中心区,在隧道开挖过程中会影响上部结构物,从而导致其发生破坏。文章基于王家坟—苏王村区间华清路以北区间段的隧道开挖工程,从超前支护和加固、洞身开挖以及二次衬砌的角度对隧道施工控制技术进行了详细的介绍,分析了隧道开挖与地表沉降之间的关系,明确了隧道开挖时控制要点,对隧道开挖质量起到了指导作用。
Subway tunnels are mainly built in the central area of the city.The superstructure are affected during tunnel excavation,thereby resulting in destruction thereof.The paper is based on interval section tunnel excavation projects on the north of Wangjiafen Suwangcun interval Huaqing Road.The tunnel excavation control technology is introduced in details from the aspects of advanced supporting and reinforcement,tunnel body excavation and secondary lining.The relationship between tunnel excavation and ground surface settlement is analyzed.The control points during tunnel excavation are made clear,thereby playing a guiding role in the quality of tunnel excavation.
