自然通风在成都南部地铁中的研究与应用

成都南部地铁区间采用地面开口的自然通风方式，在国内尚属首次。与传统的区间通风模式相比，自然通风模式可以节省初期土建、设备投资和今后的运营费用。本文对该区间自然通风的方案构思，通风井的设置形式，地面开口的大小、间距以及区间结构型式的选择等作了详细介绍。

Research on and Application of Natural Ventilation Mode in South Section of Chengdu Metro

It is the first time in China that natural ventilation modes with ventilation openings on the ground surface are used in the southern section of Chengdu Metro. Compared with the traditional ventilation modes of running tunnels，the natural ventilation modes have advantages in cost saving in respect of civil works, equipment and operation. The article gives a detailed introduction to the concept of the natural ventilation mode, the types of the ventilation shafts, the dimensions and spacing of the surface openings and selection of the types of the structures of the running tunnels.
