【摘要】 本文用模糊集方法建立了城市地震灾害风险评价的数学模型,是文献[1,2]所述风险模型在地震灾害分析中的具体应用。本文详细介绍了如何确定模糊超越率μ_z(y,x)的途径,并提供了计算承灾体灾害程度可能性分布POSS(l,y)的方法。更多还原

【Abstract】 The mathematical model of risk assessment of earthquake disaster in city is suggested by fuzzy method, which is a practical application of model in paper [1. 2]. The authors introduce a detailed way to get fuzzy riskμ (y, x ) , and provide an approach to calculate disaster possibility distribution POSS (I, y) .更多还原
