地铁车辆段试车线振动传播规律

通过对深圳市已建成运行的前海湾车辆段和横岗车辆段的试车线在运营过程中产生振动的横向传播和上盖物业的垂向传播影响进行实地监测,研究试车线在正常运营情况下的振动影响源及传播情况,结果表明,试车线振动在水平方向上的传播,均随着距离的增加而呈不断下降趋势,距离越近,衰减速率越快,距离越远,衰减越慢;振动在垂直方向上的影响分布,整体上均是随着楼层的增加而呈现下降趋势。

Study on propagation law of Vibration from Metro Depot Test Line

This paper is based on the shenzhen Qianhaiwan subway depot and Henggang Metro depot as an example, by Measuring the vibration from the test line when it is operated and analyzing the horizontal propagation and the vertical propagation of that. The results show that on the horizontal propagation the vibration from the test line is declining with the increase of distance, the closer the distance is, the faster the rate decays, the greater the distance is, the slower the rate decays. While on the horizontal propagation the vibration from the test line shows a downward trend with an increase of the floor number.
