After a major earthquake often triggers a multi-point concurrent, rapid spread of the fire. And because of the earthquake may cause fire casualties, facilities and equipment destruction, traffic jams, water pipeline damage, making the fire generally difficult to control after the earthquake. Increase earthquake disaster deaths and economic losses. And because large earthquakes are often accompanied by many aftershocks, when the main earthquake caused a fire, because the vibration generated by the earthquake in the flame combustion process may affect the flame height, pulsation frequency and intake volume, so that its combustion efficiency, delay speed and fire growth scale change, aftershocks may increase the size of the fire. However, in the literature of studying earthquake fires, most of the investigation is made on the fires that occur after the damage of building structures and fire protection equipment systems caused by earthquakes, but the vibrations generated by the earthquake have a direct lyse effect on the flame structure such as flame height, pulsation frequency and intake volume, in the literature of the flame burning phenomenon and prolonged burning in the past, and open space burning phenomenon and prolonged burning. No related studies have been found on the effects of vibration on combustion, so this study wants to use a vibrator to simulate the vibration generated by an earthquake, to conduct a series of experiments on flame combustion, from the basic flame burning phenomenon to further flame burning, and the final bedroom (confined space) fire growth pattern, to analyze the experimental results, To establish a set of basic prediction mode of fire in the event of an earthquake, so as to improve the safety of disaster relief personnel and improve the efficiency of disaster relief, and to prevent and suppress the occurrence of earthquake fires academic discussion has further results.
