摘　　要：采用TGAS模型提出了一种基于人员失能概率的安全疏散评价模型,把人员疏散和人员的失能概率结合在一起,给出了一种基于人员失能概率的多种有毒气体综合作用时危险时间的计算方法。通过算例,在给定失能概率β=0.3的条件下,展示了该评价模型在三种有毒气体综合作用时的工程应用。With the TGAS model, a kind of safety evacuation evaluation model is established based on the probability of the body disability. The evaluation model combined the probability of the body disability with the crowd evacuation. A risk time calculation method with the comprehensive effect of various toxic gases is given based on the probability of the body disabili- ty. When the probability of the body disability β is 0.3, an ex ample of the evaluation model is applied in the comprehensive effect of three kinds of toxic gases.
