According to the facts of chemical spill accidents in waterway transport, systematic analysis is made on the suitable dispersion models and source strength calculation models of multiple spilled substance, resource and environment respectively, so as to decide the poison and fire & explosion danger area of an accident through the way of dispersion simulation. to resolve the problem to the calculation of spill amount from tanks, calculation formulas on various types of tanks were worked out ; at the same time, research is carried out on the source strength calculation of mixtures with regard to the possible spillage of chemical mixture in waterway transport. for the sake of convenient application, a computer software for the simulation of dangerous area is developed which can provide great assistance to the decision - making of emergency response and reach the target of reducing the damage of the life, property and environment to the smallest degree
根據水運化學品泄漏事故的具體實際，針對各種泄漏物質、泄漏源和環境條件研究了各自適用的擴散模式和源強計算模型，以便通過擴散模擬確定事故的毒害和火災爆炸危險區域；為解決儲罐泄漏量計算困難的實際問題，推導了適用各型儲罐、液艙的泄漏量計算公式；針對化學品水路儲運泄漏事故中泄漏物質可能會以混合物形式存在的情況，探討了混合物的蒸氣釋放源強計算；為方便實用，開發了蒸氣擴散危險區域模擬計算機軟體，從而為事故應急決策提供了有力的輔助支持，以達到盡可能減少人員傷亡和財產損失，減輕環境污染的目標。
