摘要
以红松人工林的针叶为材料,在实验室内,根据之前平地无风研究的试验设计,构建不同载量、高度和含水率的可燃物床层。在各层级风速条件下,共进行100次平地点烧试验。结果表明,风速在0.9~4.6 m/s时,红松针叶床层的火强度风因子为1.769~6.708。床层压缩比、含水率对预测结果影响显著,床层载量与床层高度对预测结果影响不大。
Fuel beds composed of Korean pine needles collected from Korean pine plantations were constructed with varied fuel loading, depth and fuel moisture. Totally 100 experimental fires with these fuel beds were burned inside laboratory when wind speed is in 0. 9 - 4. 6 m/s. Un-der this range of wind speed, the wind factor of fire intensity is in 1.769 -6. 708. The results indicated that packing ratio and fuel moisture significantly influence wind factor. The effect of fuel loading and fuelbed depth on wind factor was not significant.
