摘　　要：根据地下道路的交通特性,对常规计算理论通行能力的车流计算模型进行了改进,对模型参数取值进行了修正,并分别用常规该模型和改进模型对地下道路理论通行能力进行了计算,计算结果表明,改进的地下道路车流模型是可靠的和适用的。最后,在分析基本安全和充分安全两种情况的基础上,综合其它因素,平衡安全和运行效益,提出了地下道路理论通行能力的取值标准,对地下道路的设计具有一定的参考价值。Based on the traffic characteristics of urban tunnel, the common traffic flow model has been improved, the parameters of the model has been revised in the presented paper. Furthermore, the presented paper worked out the basic capacity of the tunnel by the common traffic flow model and the improved traffic flow model respectively, the result indicates that the improved traffic flow model is reliable and applicable. Finally, after analyzing the basic safety and sufficient safety, the presented paper puts forward the criterion on basic capacity for urban tunnel under making a comprehensive view of other factors and considering balance between the safety and benefit, which will provide reference to the design of urban tunnel.
