摘要

为了合理布置铁路隧道口紧急救援站风道，以某铁路隧道口紧急救援站为工程依托，对直接将风机布置于正洞、在正洞内增设中部通风巷道和在救援平导外增设分离式通风巷道3种方案进行对比研究。结果表明：在射流风机安装牢固的前提下，直接在正洞内布置射流风机为最优方案；若考虑高速行驶列车气动荷载对射流风机的安全性影响，可考虑在救援平导外增设分离式通风巷道；在正洞内增设中部通风巷道相比于在救援平导外增设分离式通风巷道，若增设的风道较短，则造价更低，施工更方便，可根据项目具体情况采用。

Abstract

In this paper, 3 layout schemes of ventilation channel of emergency rescue station of a railway tunnel, i.e. fans in main tunnel, intermediate ventilation channel in main tunnel and separated ventilation channel in rescue parallel heading, are studied and compared. The results show that: (1) The scheme, jet fans in main tunnel, is the optimum. (2) The separated ventilation channel in rescue parallel heading can be adopted when considering the influence of aerodynamic load of highspeed trains on jet fans. (3) The shorter the ventilation channel, the lower the cost and more convenient the construction when adopting intermediate ventilation channel in main tunnel.
