Development and Prospects of Operation and Disaster Prevention Ventilation Technology in China′s Traffic Tunnels
(1. School of Civil Engineering, Southwest Jiaotong University, Chengdu 610031; 2. Key Laboratory of Transportation Tunnel Engineering, Ministry of Education, Chengdu 610031; 3. Institute of Smart City and Intelligent Transportation, Southwest Jiaotong University, Chengdu 610031)
Abstract From the perspectives of operation and disaster prevention, this paper reviews the current research status of ventilation in China's traffic tunnel operation at the levels of standards and technical methods. It summarizes the technical progress in operation and disaster prevention ventilation of traffic tunnels in China and points out the future development directions. The results show that since the new century, China's traffic tunnels have shown a development trend characterized by longer construction lengths, diversified construction environments, increased complexity of construction forms, and a shift toward lower carbon services. These trends have significantly promoted the technical progress in the operation and disaster prevention ventilation of traffic tunnels. For complex tunnel types such as extra-long mountain tunnels, high-altitude tunnels, underwater tunnels, and tunnels with curves and interchanges,a mature ventilation technology system has been developed. However, the current operational ventilation standards are somewhat lagging in matching the technological advancements in the automotive industry. In the future, the development of traffic tunnel operation and disaster prevention ventilation in China will inevitably trend towards low carbon and digital intelligence.
