摘要

目前常用的关于地铁引起的环境振动评价标准是基于单列车的计算分析结果和实测数据。而随着国内迎来了轨道交通建设的黄金时期，大量近距离多孔交叠隧道不断出现，仍沿用基于单列车的环境振动评价方法将无法真实反映实际的振动环境。武汉市轨道交通2号线与4号线工程在洪（洪山广场站）中（中南路站）区间为4孔紧邻交叠隧道，根据实际工程特点，将其中部分隧道简化为不同净距的四孔垂直隧道，建立其三维计算模型，分析了紧邻多孔交叠隧道在不同净距、不同埋深以及不同列车数量作用下的环境振动及其频谱特性，并对计算结果进行了拟合分析，建议了近似经验公式，确定了环境振动影响范围。论文研究成果可供今后类似工程的环境振动预测和评价提供参考

Abstract

At present

the commonly used ambient vibration evaluation criteria caused by train vibrating loads is based on the test data and calculation results of a single train

which can not reflect the real vibration situations with multi-tunnels because of the rapid development of rail transit in China. There are four tunnels crossing each other between Hongshan Square Station and Zhongnan Road Station

which are the second line and the fourth line of Wuhan rail transit. The complicated multi-tunnels were simplified as four adjacent perpendicular tunnels with different distances according to its practical characters. Three-dimensional calculation models are established; and ambient vibration and spectrum characteristics are analyzed with different train numbers

different tunnel depths and different tunnel net distances. Approximate empirical formulas are suggested based on the calculation results and the vibration influence areas are determined accordingly. The research results can provide references to forecast and evaluate the ambient vibration for similar projects in future in China
