N2  - METHODS for predicting the spread of fires in urban areas have been actively studied in the past, but in recent years, advances in computer technology have made it possible to perform complex calculations at high speed, so macros have been used for a long time. In addition to various calculation methods, a method of calculating the spread of fire in individual buildings by incorporating advanced calculations such as combustion phenomena and radiant heat transfer has been developed. These urban fire spread simulations are used to predict the damage caused by simultaneous multiple fires during an earthquake, to formulate firefighting activity plans in advance, and to formulate urban plans. This paper introduces some examples of urban fire spread simulation, and also uses the urban fire spread simulation software developed by the Fire Research Center for the fire 1) that occurred in Itoigawa City on December 22, 2016. The applied results are introduced.     市街地火災の延焼状況を予測する手法は従来から盛んに研究が行われてきたが，近年，計算機技術の進展によって複雑な計算を高速に行うことが可能となったため，古くから用いられてきたマクロな計算手法に加えて，燃焼現象や輻射伝熱など高度な計算を盛り込み，個々の建物の燃え広がりを計算する方式の市街地火災延焼シミュレーションが開発されている． これらの市街地火災延焼シミュレーションは，地震時の同時多発火災による市街地火災の被害予測や，消防活動計画の事前策定，都市計画の策定などに用いられている． 本稿では，市街地火災延焼シミュレーションについて幾つかの例を紹介するとともに，平成28 年12 月 22 日に糸魚川市で発生した火災1）に対し消防研究センターが開発を行ってきた市街地火災延焼シミュレーションソフトウェアを適用した結果について紹介する．<p />  <p>Language: ja</p>
