摘　　要：基于对复杂城市地下互通立交隧道特征分析,选用纵向通风方式并将复杂城市地下互通立交隧道的风流形式分为分流和合流2种,分别给出这2种形式的风流分配计算方法,提出复杂城市地下互通立交隧道通风控制标准。并将此种风流分配计算方法作为厦门海沧疏港通道-海景路隧道通风设计依据之一,量化其风机配置的标准。通过对复杂城市地下互通立交隧道风量分配计算方法进行研究,为国内城市地下互通立交隧道的通风设计提供参考,丰富国内城市地下互通立交隧道通风研究成果。Through analyzing the characteristic of urban interchange tunnel,the way of longitudinal ventilation was chosen.The ventilation form of urban interchange tunnel was divided into shunting and converging,and corresponding calculation methods were given.The control standards of the ventilation of urban interchange tunnel were presented.Moreover,this calculation method of the wind flow distribution was also used as a guideline for design of ventilation of urban interchange tunnel composed of Haicang channel and Seaview road for port evaluation in Xiamen.And the standards of the fan configuration standards were quantified.The study on the urban interchange tunnel air distribution calculation method presented in this paper can provide a reference to the design and also erich domestic research results.
