春节假期天山胜利隧道日均车流量超3.4万辆次 世界最长高速公路隧道为何超抗冻？（探访全球第一）

Core Viewpoint - The Tianshan Victory Tunnel, the longest highway tunnel in the world, successfully managed the first Spring Festival travel rush despite extreme cold conditions, thanks to a comprehensive "super anti-freeze" system designed specifically for the tunnel [1]. Group 1: Infrastructure and Design - The tunnel experienced an average daily traffic flow of over 34,000 vehicles during the Spring Festival, peaking at over 45,000 vehicles [1]. - To prevent freezing, a deep-buried central drainage system was constructed, keeping it away from frozen soil layers and reducing the risk of ice formation [2]. - A 500-meter-long insulation concrete structure was innovatively set up at the tunnel entrance, acting as a "cold-resistant wall" to maintain structural stability and ensure a safe driving environment [3]. Group 2: Monitoring and Maintenance - The tunnel features a holographic intelligent monitoring center equipped with advanced cameras that provide real-time, dynamic views of the tunnel, enhancing operational efficiency [5]. - The monitoring network allows for coordinated responses with meteorological, emergency, and fire departments, ensuring 24-hour readiness during peak travel times [5]. - The combination of robust infrastructure and advanced monitoring systems ensures that critical facilities remain operational even in extreme weather conditions, safeguarding the tunnel's functionality [5].
