基于行车模拟牵引计算的地铁区间风井设置

The Setting of Wind Wells in Subway Areas Based on Simulated Traction Calculation

什么条件下地铁地下区间中部需设置区间风井,在相关设计规范及设计标准中均没有明确规定,争议较多。提供一种基于行车模拟牵引计算、在一定研究前提条件下确定较长地下区间是否设置中间风井的理论研究方法,提出是否设置区间风井的判定标准及具体的研究实操步骤,并通过实例结果分析,明确设置区间风井的最小站间距临界值,为相关领域内的研究者、决策者及地铁建设、运营单位提供参考。

Currently, the relevant design norms and design standards concerning building wind wells in the underground zones of subway stations are not clearly defined, leading to disputes. This paper provides a theoretical research method based on driving simulation traction calculations, under certain research premises, to determine whether wind wells need to be built for long underground intervals. The study proposes the determining criteria to judge whether the wind well should be built, and the specific practical research steps. Through analysis of the example results, we clearly and effectively set the minimum critical spacing value for setting wind wells in the underground space, providing a reference for researchers, decision-makers, and subway construction and operators in related fields.
