摘  要:
通过对贮木场木材加工剩余物的燃烧蔓延规律的分析,将贮木场木材加工剩余物分布简化为多孔燃烧床。根据风和坡度对火势蔓延规律的影响情况,建立了火场燃烧形状模型,得出了火场面积、火场周边长以及增长速度公式,建立了其燃烧蔓延模型。通过模型计算与试验结果对比,证明该模型是可行的。该模型为计算机模拟技术提供理论基础,为贮木场火灾预防和减少火灾损失提供科学手段。

摘  要:
In order to explore the burning rule of timber yard,our study simplified the distribution of timber harvesting processing residues to a porous burning bed,and established the burning and spreading model.According to the impacts of wind and gradient to spreading of fire,the burning shape model of fire ground was established,the formulas for calculating the area of fire ground,the distance of fire ground surrounding and fire increasing speed were established.Through comparing the model calculation with experimental results,the feasibility of the burning model was verified.This model provided a theoretical basis for computer modeling technique,and provided a scientific way for fire prevention and decreasing the loss of fire accident.
