客运专线铁路跨越断裂带有关问题探讨
|
摘要
研究目的:客运专线铁路安全问题备受关注。我国是一个多地震国家,地震断裂带分布广泛;客运专线铁路跨越断裂带地段存在潜在安全问题,应采取适宜的工程措施和监测方法,以确保运营安全。本文以津秦客运专线为基础进行探讨。研究结论:通过对津秦客运专线跨越卢龙断裂带地段的线路平纵断面、桥梁工程、轨道型式的分析,根据地震安评报告在无震蠕滑每年位移量不大于1 mm情况下,原设计难于适应桥梁主体结构使用寿命100年、无砟轨道使用寿命60年的要求,应采用调高量大且水平和竖向均可调整的新型桥梁支座以及适应性好且非纵连的无砟轨道,同时建立平面和竖向监测网进行动态监测。
Research purposes: The safety of passenger-dedicated line becomes a focus of all society.China is a country where earthquakes occur frequently because of the widespread distribution of seismic fault zones throughout the country.There is the potential safety problems when the passenger dedicated line passing through the fault zone,so the appropriate engineering measures should be taken and the appropriate monitoring methods should be used to ensure the security of the line operation.Taking the Tianjin-Qinhuangdao Passenger Dedicated Line as an example,this paper studies the relevant issues on passenger dedicated line crossing fault zone. Research conclusions:Based on the analyses of the horizontal and longitudinal sections of the track crossing the Lulong fault zone,the bridge engineering and the track type of the Tianjin-Qinhuangdao Passenger Dedicated Line,the original design can not meet the requirements that the service life of the main structure of the bridge should be up to 100 years and the service life of the ballastless track should be up to 60 years in light of the seismic safety assessment report stipulating that the displacement of non-earthquake creep sliding is no more than 1mm.It is suggested the new-type bridge supports with large lifting height and horizontal and vertical adjustment and the adaptable and non-longitudinal connected ballastless track should be used.Meanwhile,the horizontal and vertical monitoring network should be established to conduct a dynamic monitoring.The principle of passenger dedicated line crossing fault zone is offered.
