摘要
对西安地铁2号线北(大街)～北(门)区间隧道下穿陇海铁路施工阶段的各种风险进行了探讨,重点分析了北(大街)～北(门)区间隧道的工程地质危险因素,盾构法施工的风险,盾构下穿陇海铁路施工控制措施和陇海铁路的加固措施等,可供类似工程借鉴。
Based on the construction of Xi＇an Metro Line 2, in which the interval ttmnel between the North Street and the North Gate will pass through the existing Longhai Railway un derground, the interval tunnel＇s geological risk and the shield construction risk are mainly analyzed, the construction control for shield passing beneath Longhai Railway and the reinforce ment measures are discussed, which will provide a reference for subsequent similar projects.
