摘要
21世纪以来,我国铁路隧道在设计理论与方法、标准体系、风险管理、防灾救援、建造技术等方面取得了飞速的发展和长足的进步,建成了一大批标志性隧道工程,为我国铁路的高速发展和交通强国的建设提供了有力支撑.在系统总结我国铁路隧道建设取得成就的基础上,从本质安全、建造效率、实体质量、绿色低碳等方面系统阐述了铁路隧道高质量发展的意义,并提出发展新质生产力支撑高质量发展的技术路径.为进一步提升我国铁路隧道建造水平,提出以"安全高效、内实外美、绿色智能"为主要属性特征的现代化铁路隧道工程内涵,并以提升机械化施工水平、推广主动支护体系、推行大断面施工工法、提升信息化和智能化建造水平等为主要着力点,加快形成新质生产力,着力推动铁路隧道高质量发展,为构建现代化铁路基础设施体系提供坚实保障.
Abstract
Since the 21st century,China has witnessed fast advancements and remarkable progress in the realm of railway tunnels,encompassing development in design theories and methods,standard systems,risk management,disaster prevention and rescue,and construction technology.Many iconic tunnel projects have been successfully completed,providing strong support for the rapid development of China's railway network and building China's strength in transportation.Building upon a comprehensive review of the accomplishments in railway tunnel construction within China,this paper systematically elucidates the importance of fostering high-quality development of railway tunnels,focusing on intrinsic safety,construction effficiency,works quality,and green and low-carbon practices.Furthermore,it puts forward a technical path to developing new quality productive forces and supporting high-quality development.To further enhance China's railway tunnel construction capacity,the concept of developing modem railway tunnels with attributes emphasizing safety,efficiency,structural robustness,aesthetic appeal,environmental protection,and intelligence is proposed.Improving mechanized construction capabilities,promoting the active support system,implementing the large-section construction methodology,and enhancing the capacity in informatization and intelligent construction are identified as main focus to expedite the creation of new quality productive forces,intensify efforts towards fostering the high-quality development of railway tunnels,and provide a robust foundation for establishing modern railway infrastructure networks.
