西安地铁二号线绕行通过西安钟楼，为降低地铁长期运营对钟楼的振动影响，在钟楼段采用钢弹簧浮置板道床进行减振。主要以地铁二号线运行影响下对钟楼的振动监测数据为基础，通过对钢弹簧浮置板道床段和普通道床段的振动实测值比较与分析，得出隧道内减振段和普通段的振动差异，以此评价钢弹簧浮置板道床在地铁应用中的减振效果。

Xi’an metro line 2 runs under the Bell Tower in Xi’an.In order to reduce the effect of the vibration on the Bell Tower caused by the long-term operation of the metro,a steel-spring floating slab track bed is adopted.Mainly based on the measured data,which monitors the influ-ence of the Bell Tower’s vibration under the operation of subway line 2,this paper compares and analyzes the measured values of vibration on the steel-spring floating slab track bed and usual track bed.The differences in the damping effect between the spring floating slab track bed and the usual track bed is worked out to evaluate the vibration-damping effect of the steel-spring floating slab track bed in the subway.
