The analysis and discussion on ventilation and energy-saving of the tunnels of Long Highway

Abstract Along with the construction and development of highways in China, there are more and more tunnels in the highways, and their operational security and energy-saving have been paid wide attention to. The ventilation facilities for road tunnels are very important in the construction of electromechanical facilities in the tunnels of Changda Highway, and they are the important warranting facilities for the safe operation of the tunnels in Changda Highway [1] . The problems of large energy consumption and high operation expenditure of the tunnels in Changda Highway become more and more prominent day by day. Therefore, it is very important to research the secure and economic technology of tunnel energy-saving, especially the ventilation and energy-saving technologies for tunnels. This paper is based on the engineering of extra-long Wulaoshan Tunnel in Mojiang-Lincang Highway, and it researches the ventilation and comprehensive energy-saving of the tunnels in Changda Highway – it performs the detailed analysis and research in many aspects, such as the optimized design of ventilation facilities in the tunnels of Changda Road, the intelligent control of air blower, the energy-saving power supply and distribution facilities for ventilation as well as operation and managements, and it can provide technical references for the future development of energy-saving ventilation measures of the tunnels in Changda Highway.
