单线铁路隧道软管通风技术初步试验研究

Experimental Study of the Ventilating Technique with Soft Pipes in Single-track Railway Tunnels

本文在调查研究的基础上,指出当前铁路隧道施工通风困难的各种原因,提出了长距离软管通风的新方法;总结了“引大入秦”工程实践中应用研究所取得的初步成果。

Based on field investigations, the causes of ventilation difficulties during the con- struction of single--track railway tunnels are revealed. A new methed of long distance ventilation with soft pipes is suggested, and some positive results of its application in construction practice are summa- rized.
