Abstract

Highway tunnel projects are generally built in areas with complex topography, such as mountainous and hilly areas, while the power supply in mountainous areas is relatively weak. There are some difficulties in power supply for some relatively large tunnel projects. In this paper, a practical power supply scheme of expressway is introduced to ensure that it meets the requirements of power supply, to ensure that the power supply is stable, safe and convenient to maintain.
