STUDY ON THE SUPPORT SYSTEM FOR A SAFETY PLANNING CONSIDERATION OF THE SPREAD OF A FIRE DANGER

本研究开发了一套火灾模拟系统。它不同于基于通常的火力传播速度的模型。关注每一栋建筑，模拟火灾发生和燃烧的各个阶段的火势蔓延过程。此外，还考虑了战斗火力等因素的影响。火灾的蔓延是按时间序列模拟的。因此，它是一个可能的模型，反映适用区域的实际建筑布置，设施的特点，如地震对建筑物倒塌的影响和灭火活动对火灾障碍物蔓延的影响。该模型是根据本次地震发生大规模火灾的实际情况建立的。它是通过将模拟结果与适用区域的火灾蔓延运动进行比较而建立的。与天气、建筑布置、建筑面积、结构等建筑属性、防火设施布置等有关的基础数据。提出了一种通用的作战火力训练系统，作为一种应用系统，并对火灾模拟系统进行了具体的推广。此外，还建立了灾情预测系统，对秋美机组在灾害发生时的情况进行了预测。对每种损害进行了预测分析。在此基础上，提出了城区综合危险度把握系统。老木屋拥挤区域的7个区域在这里成为了目标。随机给定100个火点，计算火灾蔓延情况。

A spread of a fire simulation system was developed by this research. It is different from the model based on the usual spread of a fire speed. It paid attention in the each building, and fire spread process was modeled on the each stage of the fire started and burned. Furthermore, the effect of the fighting a fire power and so on was taken into consideration. The spread of a fire is simulated in time series. Therefore, it is a possible model to reflect the actual building arrangement of the applicable area, the character of the facilities, an influence such as collapse of the building by the earthquake and effect on spread of a fire obstruction due to the putting out the fire activities. This model is based on the actual condition of the large-scale fire by this earthquake. It was built with comparing a result of simulation with the spread of a fire movement of the applicable area. Foundation data are in such cases as the one related to the weather, the building arrangement, the building area, the building attribute such as structure and the fireproof facilities arrangement. A general-purpose fighting a fire force training system was proposed as an application system that a spread of a fire simulation system was concrete, too. Furthermore, a damage prediction system made the conditions of Cho-me unit in the disaster occurrence. A prediction analysis against each damage was done. The system that the synthetic danger of the town district was grasped was proposed more than these results of a prediction. The 7 areas which the crowding area of the old wooden house were made the target here. 100 fire points was given to it at random, and those spread of a fire conditions were computed.
