地铁运营诱发的环境振动预测与评价——以大连地铁2号线为例

Environment vibration prediction and evaluation caused by metrooperating-taking line 2 of Dalian metro as an example

采用《环境影响评价技术导则城市轨道交通》(HJ453-2008)中的振动预测模型,以大连地铁2号线为例,对其运行期的环境振动进行了分析、预测与评价.根据评价结果,提出了不同敏感目标对应的振动防治措施,为减缓振动对周围建筑及人群的影响提出了切实可行的方案,供城市规划和建设部门参考.

This article adopts vibration prediction model in Technical Guidelines for Environmental Impact Assessment of Urban Rail Transit（HJ453-2008）,taking line 2of Dalian metro as an example,carrying on analysis,prediction and evaluation to environmental vibration of its operating period.The vibration control measures corresponding to different sensitive objectives were presented according to the evaluation results.Practical and feasible measures for slowing down the effection of vibration to surrounding buildings and crowd were proposed,and the results could provide references for urban planning and construction departments.
