高速铁路车站站台振动特性试验研究

Experimental Research on Vibration Characteristics of High-speed Station Platform

选取国内目前运营线路沿线的1个高架车站和1个地面车站为研究对象,对列车高速通过引起的站台振动进行现场测试,获得列车以350 km/h速度通过车站时,高架站台和地面站台的振动特性。测试结果表明,高架车站站台不同位置处振动均高于地面车站站台,并且不同区域特性存在较大差异;地面车站站台不同区域振动特性基本一致,Z振级平均比高架车站小6~11 dB。

Although high-speed railways in China have developed rapidly,the platform vibration caused by high-speed trains passing through deserves attention.An elevated station and a ground station along the operation line in China are selected as the research objects,and the vibration of platforms caused by high-speed passing of trains is tested on site,so as to grasp the vibration characteristics of elevated platforms and ground platforms when the train passes through the station at a speed of 350 km/h.Overall,the platform vibration of the elevated station is larger,and there is a big difference in the characteristics of different areas,while the vibration characteristics of different areas of the platform of the ground station are basically the same,and the Z weighted vibration acceleration level is smaller than that of the elevated station by 6~11 dB on average.
