摘要
针对化学危险品的事故要求能迅速地对事故的性质和可能产生危险的区域进行辨识,并能尽早地告知有关事故的性质以及可能的危险区域范围。为了快速确定事故性质及危险区域范围,通常利用应急响应系统,其核心是大气扩散模型。笔者概述了多种大气扩散模型,对当前应用较为广泛的应急大气扩散模型:SLAB,DEGADIS,ALOHA,ARCHIE,DEMRA和LPDM等作了深入剖析;对其应用作了评价;对应急大气扩散模型研究提出了建议。
Chemical accidents require a rapid identification of the nature and affected area of me accidents so as to be benefit to the rescue and evacuation. To achieve this goal, emergency response system is often used. For chemical accidents, the core of the emergency response system is atmospheric dispersion models. The current abroad-used atmospheric dispersion models are introduced, illustrated and evaluated in detail such as SLAB, DEGADIS, ALOHA, ARCHIE, DEMRA and LPDM. Related suggestions on the research of the atmospheric dispersion models are provided.
