城市轨道交通环境影响评价振动预测模型的对比

Comparison of vibration prediction models for environmental impact assessment of urban rail transit

随着城市轨道交通发展速度越来越快,众多已经开通运营的线路之中,地下线所占据比重变得越来越大,到如今的占比甚至达到了线路总长度的百分之七十。在地下线实际运营期间对于环境造成的影响主要在于环境振动,基于这种情况就需要对列车运营期间所产生的环境振动影响加以预测,这属于评价地下线环境影响之中的一个关键。

With the rapid development of urban rail transit, among the many routes that have been opened for operation, the proportion of underground lines has become larger and larger, and today the proportion even reaches the total length of the line. seventy. The environmental impact during the actual operation of the underground line is mainly due to environmental vibration. Based on this situation, it is necessary to predict the impact of environmental vibrations generated during train operation, which is a key to evaluating the environmental impact of underground lines.
