为分析城市道路隧道与公路隧道的运营风险差异，通过运营隧道调研和交通事故数据收集，从隧道本体结构及设施、外界环境、交通特性3方面出发，对城市道路隧道与公路隧道的运营风险进行阐述和对比分析。分析得出： 1）与公路隧道相比，城市道路隧道在结构方面的运营风险较大； 2）城市道路隧道车辆发生重大交通事故的概率较公路隧道低，但对城市交通的影响使其社会风险较高； 3）在城市道路隧道运营风险的防控过程中，应当重点考虑周边环境扰动对于结构安全的影响和运营交通事故所造成的社会影响。

In order to analyze operational risk difference between urban road tunnel and highway tunnel, through investigation of operational tunnel and data collection from traffic accidents, the operational risks of urban road tunnels and highway tunnels are compared from three aspects, i.e. tunnel structure and facilities, external environment and traffic characteristics. The results show that: (1) Compared with highway tunnel, urban road tunnel has greater operational risk in terms of structure. (2) The probability of serious traffic accident of vehicles in urban road tunnel is lower than that in highway tunnel, but its social risk is higher because of its influence on urban traffic. (3) In the process of prevention and control of urban road tunnel operation risks, the impact of surrounding environmental disturbances on structural safety and the social impact of operating traffic accidents should be considered.
