摘　　要：海底隧道在运营期面临诸多复杂环境安全问题,基于青岛胶州湾海底隧道实际运营状况的实测数据进行分析,采用现场空气质量、噪声测试等方法,结合隧道实际通风需求,对隧道内部空气环境评价、周边声环境评价以及海底隧道特有的渗水排放量等综合运营环境指标进行研究。结果表明隧道内良好的通风系统保障了有害气体CO的浓度满足运营要求;日益增加的车流量对隧道进出口产生的噪音已经超过限值,需进行处理;隧道渗水日均排放量维持在4000 m 3左右,满足隧道安全运营要求。Submarine tunnel in operation period has complex environmental safety problems,based on the experimental data analysis of Qingdao jiaozhou bay submarine tunnel actual operation situation,take the method of the air quality test,near tunnel noise test,and combined the reality of tunnel ventilation requirements,the tunnel water seepage discharge evaluation of unique comprehensive operating environment were researched.The result showed that the good ventilation system in the tunnel ensured the CO concentration meet the operation requirements.The growing traffic volume made traffic noise at tunnel exits exceeded the normal value,and need protect with sound barrier;The average daily discharge of seepage water in the tunnel was maintained at 4000 m 3,it can meet the safety operation requirements of the tunnel.
