Description
Technical field
Invention is related to railway tunnel technical field of fire hazard safety, more particularly to one kind containing a plurality of evacuation transverse passage-way railway tunnel
Road rescue station fire test system, flue gas control effect during for resting in rescue station after train fire in extra-long railway tunnel
Simulated, can be achieved to temperature field, the measurement of velocity field.
Background technology
Railway is the important infrastructure of country, main artery, the popular vehicles as country, in comprehensive traffic
Be in key status in system, and one of the important component of tunnel as railway, in recent years its quantity be on the increase and
Single seat length of tunnel also constantly increases.Although compared to vcehicular tunnel, the probability that fire occurs for railway tunnel is smaller, by
In its buried underground, environment closing, all it is greatly limited in ventilation, passenger flow rapid evacuation etc., once fire occurs
Calamity, dense smoke and hot gas are difficult that nature excludes, if the intensity of a fire can not be controlled effectively, its consequence will be hardly imaginable.
In view of the randomness and harmfulness of tunnel fire hazard, in railway tunnel particularly extra-long railway tunnel, carry out tunnel
Fire prevention and Evacuation Design work are extremely important, and for extra-long railway tunnel, setting rescue station is preferentially examined in Fire prevention
The scheme of worry.The working mechanism of rescue station is：When in tunnel fire occurs for train, train is left for into rescue station in time, multiplied
Visitor and road man get off rapidly, are evacuated to another tunnel, waited for rescue by transverse passage-way.Therefore, train stop of catching fire is studied
After rescue station under different fume exhausting types the regularity of distribution in temperature field, Smoke Spread and flue gas control effect for railway of growing up
Tunnel rescue station Fire prevention has important directive significance.
Economy and facility is tested based on small-scale model, it has also become the conventional means of research railway tunnel fire test now,
Have some researchers both at home and abroad and carried out various forms of model fire tests.External aspect, Lee et al. (1979) are built
Found an a length of 13.7m, the small size test model that cross-sectional area is 0.27m2, and to suppressing tunnel fire disaster fume adverse current
Critical wind velocity is studied.Afterwards, Chaiken et al. (1979), Vantelon et al. (1990), Kwack et al. (1990),
Xue et al. (1993), Oka et al. (1996) establish a series of small size test model that scales differ in succession, go forward side by side
The correlative study of tunnel fire hazard is gone.Hwang and Wargo (1996) have studied influence of the tunnel top rake to flow of flue gas.
G.T.Atkinson and Y.Wu (1996) have studied influence of the top rake to critical air-supply wind speed, and proposes and consider tunnel longitudinal slope
The projected relationship formula of the critical air-supply wind speed of degree.Y.Wu and M.Z.A.Bakar (2000), Hitoshi Kurioka et al.
(2002) detailed grind has been carried out to tunnel fire plume inclination angle, ceiling highest flue-gas temperature and position to vertical wind speed respectively
Study carefully, and propose the rule-of-thumb relation of oneself.Vauquelin (2006) passes through 1:20 model test, have studied tunnel width
Influence to critical wind velocity.Jae Seongroh (2008) establish one 1:20 small size testing stand, and have studied ventilation
Influence of the wind speed to burning things which may cause a fire disaster burn rate.Domestic aspect, it is 1.8m that the Yan Zhiguo (2002) of Southwest Jiaotong University, which establishes internal diameter,
Wall thickness is 15cm, a length of 100m concrete reinforced pipe segment model tunnel, and by the fire test of tunnel model, fire is occurred
When tunnel in the distribution of temperature field and pressure field, the condition of smog studied.Wang Mingnian of Southwest Jiaotong University etc.
(2003) an a diameter of 2m is established, length 120m, the gradient is 1% model tunnel, during to fire occurring in tunnel
Temperature changing regularity is studied.Lee's winter (2010) of Central South University using lion ocean submerged tunnel to rely on, establishes ratio
For 1：9, length is 52.5m model tunnel, and the Disaster Prevention Design and Fire prevention of underwater shield tunnel are studied.
By being investigated to some data, at present for the research of tunnel fire hazard, focus mostly on and occur in fire in single tube
The situation in tunnel, as the B of Chinese invention patent document CN 102306459 also merely disclose single tube railway tunnel rescue station fire
Experimental system for simulating；Research for fire test in the rescue station provided with evacuation transverse passage-way connection double-hole tunnel is also almost empty
In vain.
