摘　　要：厦门嘉禾路地下行车通道埋深浅,施工时要保证上方的正常交通,因此如何预测地下通道在交通荷载情况下动力响应显得很重要。运用有限元分析方法对城市地下通道在交通荷载作用下所产生的影响进行分析,并与现场动力响应实测数据相对比,结果表明交通荷载引起的地中动力响应和附加应力增幅较小,同时可得出土压静载是结构设计的控制荷载。The underground driving passage in Jiahe Road of Xiamen is shallow-embedded. It is important how to forecast its dynamic response under the transportation load because the normal transportation above it must be guaranteed in construction. The finite element method is used to analyze the influence produced under the transportation load about urban underground passage and compare with the measured data in site. The results indicate that the dynamic response and aditional stress in ground produced by the transportation load increase a little, and the static load is the control load in a structural design.
