摘　　要：考虑了应力服从三维GBVE分布,强度服从指数分布的应力-强度模型,分别在部分应力参数未知和强度参数未知的情况下给出了该模型在并联情况下结构可靠度的估计,并讨论了其性质。The stress strength model with stress consistent with three-dimensional GBVE distributed and strength exponentially distributed was considered.In the case of partially unknown stress parameters and unknown strength parameter,estimation of structural reliability for the model is proposed in parallel condition,their properties are discussed respectively.

关 键 词：结构可靠度 三维GBVE分布 相合性 渐进正态性
