摘要
当前,隧道疏散通道及其横通道(前室)相关通风规范只有防烟设计要求,尚无设计实施细则,致使设计常常无从下手。以现行规范、标准为基础,通过分析民用建筑防烟楼梯间和隧道疏散通道的共同点和差异性,隧道横通道防火分隔采用何种防火门的争议与取舍,建立单洞双向隧道防烟设计CFD模型,给出具体的防烟设计过程。本研究可作为包括双洞单向隧道在内的城市、山岭隧道防烟设计参考。
At present,the ventilation specifications related to the tunnel evacuation passage and its transverse passage(front room)only have the requirements of smoke prevention design,and there are no design implementation rules,so the design is often out of the way.Based on the current codes and standards,this paper analyzes the similarities and differences between the smoke proof staircases and the tunnel evacuation passageways in civil buildings,and the dispute and choice between the fire door or the fire rolling shutter door in the tunnel cross passage,establishes the CFD model for the smoke prevention design of single hole two-way tunnel,and gives the specific smoke prevention design process.This study can be used as a reference for smoke control design of urban and mountain tunnels including double tunnel and one-way tunnel.
