蓝商高速公路穿越秦岭,承东启西,是连接东南沿海的主通道,日平均车流量达万辆,全线92.315km,全线双向四车道,共计隧道35座,其中特长隧道2座全线桥隧占路线总长度的37%,沿线路况复杂,路线最小平曲线半径450m、反向曲线间多采用“S”形曲线。再加上天气、气候的多变,致使蓝商高速公路经常发生事故。为此隧道安全管理工作一直是蓝商分公司运营管理的难点和重点,本文以李家河隧道群、秦岭隧道实际情况,对特长隧道安全管理的进行了论述。
The Lanzhou Expressway runs through the Qinling Mountains and runs through the east and the west. It is the main thoroughfare linking the southeast coast with an average daily traffic of 10,000 vehicles, covering a total area of 92.315km with four lanes of four lanes and a total of 35 tunnels, of which 2 are full tunnels Accounting for 37% of the total length of the route. The road conditions along the route are complex with the minimum horizontal curve radius of 450m and the “S” -shaped curve is often used between the reverse curves. Coupled with the weather, climate change, resulting in frequent accidents Lan Business Expressway. To this end, tunnel safety management has always been a difficult and important point for operation and management of Lan Branch. In this paper, the safety management of long tunnel is discussed based on the actual situation of Lijiahe Tunnel Group and Qinling Tunnel.
