A Study On Wushaoling Tunnel's Auxiliary Gallery Influence On Operation Ventilation And Long Tunnel Rescue Station Disaster Prevention Research

Long railway tunnels mostly sets auxiliary gallery. Tunnel and auxiliary gallery forms complex ventilation network. However, there is no perfect method for network ventilation design calculation of railway tunnel. With more and more of the railway tunnel construction, the long railway tunnel ventilation design calculation in the case of many auxiliary gallery conditions and ventilation under the influence of the auxiliary gallery and rescue station becomes the problem to be solved. This thesis combined with the auxiliary gallery settings in Wushaoling tunnle study on above problems, draw some useful conclusions.Thesis mainly includes four aspects: the network ventilation calculation method of railway tunnel, the calculation of ventilated power, Wushaoling tunnle's auxiliary gallery influence on ventilation, long railway tunnel disaster prevention with rescue station.In order to solve the long railway tunnel ventilation calculation, thesis first introduced network ventilation calculation theory. According to the air balance and wind pressure balance equation, the mathematical model is established, draw a set of suitable for railway tunnel ventilation calculation method.Then the calculation of wind power are studied, including the wind power through operation mode and others through the fire mode, etc. Through the investigation and analysis, the key to train piston wind was analyzed, also use numerical calculation and in-situ test, studied the piston wind.And combined with the auxiliary gallery settings in Wushaoling tunnle, the influence on ventilation and how to use it is studied in detail.Finally the long railway tunnels disaster prevention with rescue station is researched, including the form, design mode and the research of rescue station in Taihangshan tunnel.
