摘要
上海市已经率先开展了城市轨道交通的运营安全评价工作.通过整理评价结果,发现运营中的土建系统设备和结构均发生了老化,产生了病害.其中典型的问题有：钢轨出现了不同程度的伤损和波磨,其具体伤损类型受运营年限和环境等因素的影响;土建结构产生了沉降,并且整体趋势随时间逐渐趋于稳定;隧道结构发生了沿水平径向拉伸的变形,且变形量普遍在0～6 cm之间.
Shanghai has taken the lead in urban rail transit operation safety evaluation. Through summarizing the evaluation content, the deterioration phenomenon in both the construction devices and the structure are detected, the aging equipment and structure have reduced the operational reliability. The typicai problems include rail grinding wave and injuries in different degrees, which are directly influenced by the operation period and environment; but the settlement of construction structure will tend to be stable with the change of times,because the horizontal radial stretching happens in tunnel structure deformation, and the amount of deformation is within 0-6 cm in general.
