本文提出了一个以允许延性比为控制指标的浅埋防护结构动力可靠性分析方法,利用一次二阶矩理论计算防护结构的浅埋工事的破坏概率。讨讨了影响结构生存概率的一些无量纲参数,并提出了一些供防护结构概率设计参考的建议。
This paper proposes a dynamic reliability analysis method for shallow buried structures with the allowable ductility ratio as the control index, and uses a second-order moment theory to calculate the damage probability of shallow-buried structures for protective structures. Some dimensionless parameters that influence the survival probability of the structure are discussed, and some suggestions for the probabilistic design of the protective structure are proposed.
