摘要
以新建沪宁城际铁路客运专线为例,介绍了城际铁路客运专线无砟轨道线下工程控制测量的技术方案及沉降观测评估的评估分析标准、评估内容;在分析管桩+筏板路基地段采用堆载预压土加固方法时,利用主体工程完工后不少于3个月的有效观测时间进行线下工程沉降评估的可行性。
Taking the newly-built Shanghai-Nanjing Passenger Dedicated Line for example,technical program for control and survey of ballastless track substructure engineering of intercity railway passenger dedicated line as well as settlement evaluation standard and content are introduced in this paper.When analyzing preloading reinforcement for the section with pipe pile and raft,it is feasible to evaluate substructure settlement for no less than 3 months after completion of main work.
