上海磁悬浮快速列车环境振动影响探讨

通过对磁悬浮快速列车沿线两侧区域振动监测,得出振动级VLzmax与列车速度有较好的相关性,实测得出了振动随车速变化的衰减系数。同时给出了振动随离轨道距离变化的衰减方程,参照现有环境振动国家标准,给出了不同车速下磁悬浮轨道两侧区域的振动达标距离。

The Analysis of Environmental Impact for Maglev Vibration in Shanghai

According to the measurement of environmental vibration along the maglev, the relation between the degree of vibration and the speed of maglev appears obvious. At the same time, the declination coefficient for different speed comes out. The formula of vibration changed with distance is obtained in terms of weakening vibration by shortening distance. Referring to the Actual Standard of China, estimated statistics is achieved based on varying maglev speed observed from the survey area.
