摘要 研究目的：山区地质条件复杂、环境敏感脆弱,致使铁路隧道修建在环境保护、水土保持等方面任务艰巨,降低隧道建设对区域环境的扰动、平衡隧道建设与环境稳态之间的关系势在必行。为明确“隧道-环境”绿色协调发展的关键节点,以制定针对性策略降低隧道建设对区域环境的不利影响,提出一种基于多层耦合网络模型的山区铁路“隧道-环境”关键绿色要素分析方法。
研究结论：(1)在明晰山区铁路“隧道-环境”交互影响关系的基础上,构建包含隧道绿色要素、接口要素、环境要素的要素体系,运用多层耦合网络模型,将各要素抽象为不同层次网络的节点,并建立各节点层内层间的有机联系,可为实现“隧道-环境”交互影响关系的定量表达建立基础;(2)以某山区铁路隧道工程为例,运用网络节点重要性评估方法,识别出7个关键绿色要素：隧道断面尺寸、隧道掘进长度、隧道爆破方式、隧道通风方式、隧道衬砌防水设计、隧道注浆堵水、隧道通风设备布设,应对其进行优化控制;(3)研究结果符合工程实际,验证了模型的适用性,可为明确降低山区铁路隧道建设对区域环境胁迫效应的着力点提供评判依据。

Abstract：Research purposes: The complex geological conditions and fragile environment in mountainous areas make the construction of railway tunnels arduous in terms of environmental protection, soil and water conservation, etc. It is imperative to reduce the disturbance of tunnel construction to the regional environment and balance the relationship between tunnel construction and environmental stability. To clarify the key nodes of green coordinated development of "tunnel-environment" and formulate targeted strategies to reduce the adverse impact of tunnel construction on the regional environment, an analysis method of key green elements of "tunnel-environment" in mountain railway based on a multi-layer coupling network model is proposed.
Research conclusions: (1) Based on clarifying the interaction relationship of the "tunnel-environment" in mountain railway, build an element system that includes tunnel green, interface, and environmental elements. Using the multi-layer coupling network model, each element is abstracted as the node of the network at different levels, and the organic relationship of each node in and between the network layers is established, which can establish the basis for the quantitative expression of the interaction relationship of the "tunnel-environment". (2) Taking a railway tunnel engineering in a mountainous area as an example, the network node importance assessment method is used to identify seven key green elements: tunnel section size, tunnel excavation length, tunnel blasting mode, tunnel ventilation mode, tunnel lining waterproof design, tunnel grouting and water plugging, tunnel ventilation equipment layout, which should be optimized and controlled. (3) The research results are in line with the engineering practice, and verify the applicability of the model, which can provide a basis for determining the key points to reduce the stress effect of railway tunnel construction in mountainous areas on the regional environment.

Key words： railway tunnel in mountainous area regional environment multi-layer coupling network model key green elements
