Comparative Analysis of Ventilation Modes for Long Tunnels with Small Diameter
The purpose of this paper is to deeply analyze the selection of ventilation mode in the construction of long tunnel with small diameter in water conservancy projects.Through the analysis of pressure-in,suction-out and mixed ventilation,the differences in ventilation effect,energy consumption,safety and other aspects of the three ventilation methods are discussed.Through comparative analysis,it can provide a reasonable basis for the selection of ventilation schemes for long tunnels with small diameter in similar water conservancy projects.
