【摘要】：随着我国城市公路交通快速发展，大型地下互通式立交隧道不断涌现。大型地下互通式立交隧道，具有缓解地面交通压力、减少地面交通拥堵、保障城市交通快捷和改善城市环境等功能。但随着地下立交分支数量的增多、长度的增加、规模的增大和形式越来越复杂，，其通风系统设计已经成为地下立交隧道建设和安全运营必须研究的重要问题。 本论文首先介绍了地下互通式立交的形式、类型和相关设计参数；其次，以网络通风理论为基础，结合公路隧道通风的特点，研究了大型地下互通式立交隧道通风设计的有关问题，建立了大型地下互通式立交隧道通风网络计算模型；再次，研究编制了大型地下互通式立交隧道通风系统设计软件，该软件能够进行各种复杂形式的大型地下互通式立交隧道通风计算；最后，以某大型地下互通式立交工程为依托，运用编制的通风软件系统进行通风计算和动力配置，所得通风系统配置满足运营通风要求。本文的研究，为大型地下互通式立交的通风系统设计提供了一个系统方法和便捷的计算手段，为地下互通式立交通风系统设计和运营通风系统控制提供技术支持。
[Abstract]:With the rapid development of urban highway traffic in China, large underground interchange tunnels continue to emerge. The large underground interchange tunnel has the functions of relieving the ground traffic pressure, reducing the ground traffic congestion, ensuring the urban traffic quickness and improving the urban environment. However, with the increase of the number, length, scale and form of underground interchange branch, the design of ventilation system has become an important problem that must be studied in the construction and safe operation of underground interchange tunnel. This paper first introduces the form, type and related design parameters of underground interchange. Secondly, based on the theory of network ventilation, combined with the characteristics of highway tunnel ventilation, The ventilation design problems of large underground interchange tunnel are studied, and the ventilation network calculation model of large underground interchange tunnel is established. Thirdly, the ventilation system design software of large underground interchange tunnel is developed. The software can calculate the ventilation of large underground interchange tunnel in various complicated forms. Finally, based on a large underground interchange project, the ventilation calculation and dynamic configuration are carried out by using the ventilation software system. The resulting ventilation system configuration meets the operational ventilation requirements. The research in this paper provides a systematic method and convenient calculation method for the ventilation system design of large underground interchange, and provides technical support for the design and operation ventilation system control of underground interchange ventilation system.
