价值工程在高铁隧道优化中的应用研究

Value Engineering Application on High-Speed-Rail Tunnel Optimization

以隆新高速铁路设计为背景,基于价值工程功能分析理论,应用专家知识和群决策(DSS)技术,通过对案例设计方案进行系统的研究,建立了一个多因素影响的隧道优化设计方案理论模型,并基于此模型对隧道的功能和成本进行评价,得出相应的评价指标,应用于隧道设计之中。在不增大隧道断面尺寸的情况下将隧道两侧的水沟电缆槽道加高460 mm,作为疏散通道,实现了灾害工况下人员安全快速疏散至隧道两侧疏散通道的目的。提出了一种基于复杂价值工程的高速铁路隧道设计方案比选和优化模型。

Based on value engineering analysis in Kuala Lumpur-Singapore High-Speed-Rail,a tunnel optimized design theoretical model responding to multi-factors was proposed through a case study,within expert knowledge and group decision support system.After obtaining corresponded parameters of function and cost assessment,the research can be applied in tunnel design.The conclusions are as follows.Within original cross-section,the walkway on cable trough can be lifted 460 mm higher to ensure passengers and staffs safely passing-by in case of accidents.The new tunnel optimized design and model are generated based on value engineering,which offers a standard reference for tunnel engineering.
