基于系统工程方法论的川藏铁路隧道工程建设管理探讨

为全面提升应对川藏铁路隧道工程建设中复杂问题的能力和手段,以时间维、逻辑维、知识维以及环境维为基础结构,建立了基于系统工程方法论的川藏铁路雅安至林芝段隧道工程建设管理体系。结合川藏铁路隧道工程面临的主要挑战,根据时间维的不同阶段和逻辑维的目标实现,通过知识维的技术积累和研究攻关,系统总结了针对工程勘察与设计、特殊不良地质、施工组织和建设管理等重点问题的对策措施,以期为川藏铁路雅安至林芝段隧道工程的建设管理提供参考。研究表明:(1)隧道工程在川藏铁路全线占据主导地位,应建立基于系统工程方法论的全周期建设管理体系;(2)川藏铁路隧道工程的技术挑战主要是特殊复杂的地质环境,相关解决方案应在可研和设计阶段提出,在实施阶段深化应用研究,以确保对策措施的有效可靠;(3)鉴于川藏铁路隧道工程严酷的环境条件、极端的地质挑战和超长的建设周期,需要更高水平的"四化"支撑和突破性管理创新;(4)鉴于川藏铁路隧道工程建设管理问题的复杂性,任何一个参建方都不可能独立应对这一巨大系统工程的管理风险,需要建立更高层次的全周期一体化管理机制,实行更严格的生态环境保护,组织更有力的科技创新支撑。

Discussion on the Construction Management of Sichuan-Tibet Railway Tunnel Based on System Engineering Methodology

In order to comprehensively improve the ability and means to deal with the complex problems in the con?struction of the Sichuan-Tibet railway tunnel project,a tunnel construction management system for the Ya′an-Lin?zhi section of the Sichuan-Tibet Railway is established based on system engineering methodology by taking time di?mension,logical dimension,knowledge dimension and environmental dimension as the basic structure.Aiming at the main challenges faced by the Sichuan-Tibet railway tunnel project,it systematically summarizes the countermea?sures for the key issues of engineering survey and design,special unfavorable geological condition,construction or?ganization and management in view of the different stages of time dimension,goals of logical dimension and through technology accumulation and research of knowledge dimension,providing a reference for the construction and manage?ment of tunnel project of Ya′an-Linzhi section.The research indicates:(1)the tunnel project is critical for the entire Sichuan-Tibet Railway,and so a system engineering methodology based full-cycle construction management system should be established;(2)the main technical challenge of the Sichuan-Tibet railway tunnel is the special complex geological condition,related solutions should be put forward in the feasibility study and design stages and further application research should be conducted in implementation stage to guarantee effectiveness and reliability of the countermeasures;(3)in light of the harsh environmental conditions,extreme geological challenges and super-long construction period of the Sichuan-Tibet Railway tunnel,a higher level of“Four Modernizations”and breakthrough in management innovation are required;(4)aiming at the complexity of the construction and management of the Sichuan-Tibet railway tunnel,no participant can independently handle the management risks of this huge system project and it is necessary to establish a higher-level full-cycle integrated management mechanism,implementing stricter ecologi?cal environmental protection and organizing stronger scientific and technological innovation support.
