【摘要】：已建和待建的多条地铁线路穿过某房地产开发地块,为了防治地铁运行对建筑造成振动环境影响,需要设定建筑靠近地铁的最小达标距离,包括采取减振措施后的距离。通过现场系统实验监测结合数值模型分析,从工程实践的角度提出了上述距离。对于实验中观察到随距离出现振动局部放大以及进口与国产仪器监测结果不同的现象,佐证了有关学者的理论与实验分析,提出:(1)现有地铁环境影响评价报告常用的60m评价范围偏小,推荐可扩大至80~100m;(2)迫切需要新的振动环境标准发布,避免有关项目的环境管理要求偏低。
[Abstract]:Many subway lines that have been built and ready to be built pass through a real estate development plot. In order to prevent the vibration environmental impact caused by subway operation, it is necessary to set the minimum distance between the building and the subway. It includes the distance after the vibration reduction measures are taken. The field system experiment monitoring is combined with the numerical model analysis. The above distance is put forward from the point of view of engineering practice. The phenomenon of local amplification of vibration with distance and the difference of monitoring results between imported and domestic instruments are observed in the experiment, which proves the theoretical and experimental analysis of relevant scholars. It is suggested that the commonly used 60m evaluation range of the existing subway environmental impact assessment report is small, and the recommendation can be extended to 80m / 100m. 2) there is an urgent need for new vibration environmental standards to be issued to avoid low environmental management requirements.
