Optimization Analysis of Operating Ventilation Network Simulation of Zhegu Mountain Tunnel

Chuan He

Abstract

The optimization study on operating ventilation's plan of Zhegu Mountain Tunnel in National Highway 317 are carried out by ventilation network theory and performs.At the same time,four ventilation plans are brought forward according practical situations of this project and simulated considering such two situations as air natural distribution and control air distribution,then the effects of natural ventilation pressure on operating ventilation of tunnel are studied.The findings indicate that it is possible to optimize the operating ventilation plan of Zhegu Mountain Tunnel and jet settings in tunnel should vary with the natural ventilation pressure.
