Improving the management of tunneling operations in urban areas of Vietnam

Abstract

Nowadays, in Vietnam's major cities, making use of underground space (tunnels) in road traffic is necessary, especially at river crossings or at complex intersections with high traffic density. However, there have been many problems in the operation, exploitation and maintenance of traffic tunnels due to damages such as cracks in the tunnel shell, water infiltration, flooding, fire and explosion, causing traffic insecurity, which needs to be further considered and perfected, especially the safety of people and vehicles traveling through the tunnels. The drafting of management procedures for tunnel works has some limitations in the operation process, because the tunnel operation process contains many potential risks that can lead to risks affecting the function, the existence of the work and the damage to human life and property, the cost and time for the maintenance. This article focuses on perfecting the management process of tunneling operations in order to contribute to ensuring stability, longevity, workability and efficiency when operating tunnels in general and urban traffic tunnels in particular.
