摘　　要：从京津城际铁路开通至今的十余年间,我国高速铁路迅猛发展,“八纵八横”铁路网即将实现。与此同时,铁路基础设施状态检测监测体系也逐步完备。随着检测运维技术智能化的不断深入,在现有评估技术的基础上,基于模数驱动形成了高速铁路线路设备全生命周期运维总体架构,实现了依托联调联试动态验收形成的包含轨道几何状态、钢轨短波状态、轮轨力响应等在内全方位、多层次的线路状态评估与验收技术;以周期性运营检测为基础,形成了包含线路长期服役状态跟踪、典型病害识别、关键设备状态评价等在内体系完整、覆盖全面的服役状态确认技术;针对长服役年限线路,提出多种维修决策技术,形成了包含轨道几何、钢轨短波不平顺、轮轨力、道岔等在内多角度、多维度的提质改造后线路服役状态确认体系。依托高速综合检测列车的动态检测技术,覆盖新建线路状态验收、运营线路状态评估、线路提质改造后状态确认的高速铁路线路设备全生命周期状态检测评估技术已经形成并将在实践中不断发展完善。Over the past decade since the opening of the Beijing-Tianjin Intercity Railway,China’s high speed railways have developed rapidly,and the railway network featuring“eight south to north lines”is on the verge of realization.Correspondingly,the state monitoring and detection system for railway infrastructure has gradually become complete.With the continuous advancement of intelligent detection and operation and maintenance(O&M)technology,based on existing assessment technologies,this paper proposed a comprehensive lifecycle O&M architecture for high speed railway line equipment driven by modulus,and a comprehensive and multi-level line state assessment and acceptance technology was formed based on the dynamic acceptance of joint debugging and testing,which included track geometry state,short-wave rail state,and wheel-rail force response.Through periodic operational testing,a complete and comprehensive service state confirmation technology was formed,covering long-term service state tracking of the line,identification of typical diseases,and assessment of key equipment state.For lines in long-term service,a variety of maintenance decision-making technologies were proposed,forming a multi-angle and multi-dimensional service state confirmation system after quality improvement and transformation,including track geometry,short-wave rail irregularities,wheel-rail forces,and turnouts.With the help of the comprehensive dynamic detection technology of high speed trains,the full lifecycle state detection and assessment technology for high speed railway line equipment was formed and will continue to develop in practice,covering the acceptance of new lines,the assessment of operational lines,and the confirmation of service state after line quality improvement and transformation.
