隧道穿越特殊地质路段时,在开挖过程中容易产生突发性工程事故,直接威胁到现场施工人员和施工机械设备的安全。为了减少在开挖过程中发生突发性工程事故,以山西省公路第一长隧道、全国公路第二长隧道——西山特长隧道(长13.65km)为工程实例,介绍了隧道穿越软弱围岩及断层破碎带路段的衬砌结构方案设计及施工防治措施,重点提到了超前帷幕注浆设计及施工的关键技术,可供同类工程方案设计和施工防治措施提供借鉴和参考。
When crossing the special geological sections, the tunnel is prone to sudden engineering accidents during excavation, which directly threatens the safety of on-site construction workers and construction machinery and equipment. In order to reduce sudden engineering accidents during excavation, taking the first long tunnel of Shanxi Province and the second long tunnel of China National Highway - Xishan Special Tunnel (length 13.65km) as an example, the tunnel crossing soft rock And the design of the lining structure of the fault broken belt section and the construction prevention and control measures, the key technologies of the design and construction of the advanced curtain grouting are emphatically mentioned, which can be used for reference and reference for the design and construction of similar projects.
