HJ 453-2008《环境影响评价技术导则城市轨道交通》中给出的地铁环境振动预测模型在实际使用中存在着诸多不便,如:修正量因取值范围较大而不易确定,尚未提及曲线轨道和列车加减速的影响等。为此,在HJ 453-2008现有振动预测模型的基础上,结合北京地铁实际运营特点,基于大量地铁振动实测数据的对比统计分析,提出了一个适用于北京地铁的环境振动预测模型。经与北京地铁实测数据相比,验证了该预测模型的精度满足要求。该预测模型的建立有助于进一步完善北京市地铁振动预测和环评工作。
HJ 453-2008 “Environmental Impact Assessment Technical Guidelines for Urban Rail Transit” gives metro environmental vibration prediction model in actual use there are many inconveniences, such as: the amount of correction due to a large range and not easy to determine, has not yet mentioned Curve track and train acceleration and deceleration and so on. Based on the existing vibration prediction model of HJ 453-2008 and based on the actual operation characteristics of Beijing Subway, based on the comparative statistical analysis of a large number of measured data of subway vibration, an environmental vibration prediction model suitable for Beijing Subway is proposed. Compared with the measured data of Beijing Subway, the accuracy of the prediction model is verified to meet the requirements. The establishment of this prediction model will help to further improve the subway vibration prediction and environmental impact assessment in Beijing.
