国内外公路隧道火灾排烟设计理念比较

目前，普遍采用的排烟模式有纵向排烟模式和集中排烟模式，其烟气控制原理与适用范围各不相同。国内外公路隧道火灾排烟设计理念差距较大，国内（除香港外）公路山岭隧道普遍采用纵向排烟模式，而欧美发达国家则更趋向于采用集中排烟模式。相比纵向排烟模式，集中排烟模式虽然会增加工程投资，但是其排烟效果和防灾能力具有明显优越性。

Comparison of Domestic & Overseas Design Concepts for Smoke Exhaust in Expressway Tunnels Fires

As of now the smoke exhaust modes universally adopted are classified into longitudinal smoke exhaust mode and centralized smoke exhaust mode,their smoke control principles and applicable ranges are different to each other.There is large disparity between domestic and abroad fire smoke exhaust design ideas for expressway tunnels,all expressway mountain ridge tunnels at home(except Hong Kong) use the longitudinal smoke exhaust mode,otherwise the American and European developed countries prefer to the centrali...
