作者不久通过模型巷道的实验,调查了各种条件对巷道火灾蔓延特性的影响,明确了蔓延速度、火灾长度等有代表性的蔓延特性值与着火源强度、通风速度、可燃物量、巷道倾斜及通风方向的关系。所使用的实验装置按1/6到1/12比例缩小的模型,根据相似法则确定实验条件,在研讨实验结果时对现象的相似性给予十分重视。然而,可燃性固体的燃烧现象伴随着很多复杂反应,完全模型化是不可能的,尽可能在有实际规模的巷道进行实验,以期待一般性的验证。 巷道火灾实际规模的实验,除我国(日本)之外,如西德、美国及英国等都有试验
Soon after, the author investigated the influence of various conditions on the spread of fire in tunnels by experiments on the model roadway, and clarified the representative spread characteristics such as spread speed, fire length, ignition intensity, ventilation speed, combustible material quantity, roadway inclination And the direction of ventilation. The experimental device used is a 1/6 to 1/12 scale reduction model, and the experimental conditions are determined according to the similarity rule. The similarity of the phenomena is paid more attention when discussing the experimental results. However, combustion of combustible solids is accompanied by many complicated reactions. Complete modeling is not possible. Experiments in real-scale tunnels are conducted as far as possible to expect general validation. In addition to our country (Japan), experiments such as West Germany, the United States and the United Kingdom all have experiments on the actual scale of roadway fires
