北京城市轨道交通地下线振动影响预测分析及建议

Beijing Underground Rail Transit Vibration Impact Analysis and Mitigation Suggestions

通过分析研究轨道交通振动程度与线路埋深、距离及行驶车速等工程因素的关系,结合北京市轨道交通工程实况及其环境影响技术评估实践,总结了采取减振措施的思路和原则,以期指导北京市城市轨道交通环境影响评价、振动控制工程设计等相关工作,提高环境影响评价指导城市轨道交通振动控制及防治措施的有效性,使振动控制效果和经济投入的平衡点更加科学、合理、可行。

Based on the analysis of influencing factors of vibration such as depth,distance and speed,the engineering status quo of Beijing rail transit,and the EIA practice,this paper summarizes ideas and principles for vibration mitigation in order to guide the Beijing urban rail transit EIA and the vibration control engineering design,improve the effectiveness of EIA in controlling and mitigating the vibration,and lead to more scientific,reasonable and feasible vibration control investment.
