【摘要】：极端事件和结构恶化导致的桥梁结构失效事故频发,造成的经济损失不可估量。针对桥梁结构选取结构的极限承载能力作为功能函数指标,提出基于经验调查的线性模型和基于力学比拟的拟合模型两种功能恢复函数,在此基础上建立灾害可恢复性指数来衡量桥梁结构灾害可恢复能力的大小;并给出桥梁灾害可恢复性的建议分级标准,为我国现阶段桥梁防灾抗灾设计提供新的思路和参考。
[Abstract]:The failure accidents of bridge structures caused by extreme events and structural deterioration occur frequently, and the economic losses are inestimable. Aiming at selecting the ultimate bearing capacity of bridge structure as the index of function, two functional recovery functions, linear model based on empirical investigation and fitting model based on mechanical analogy, are proposed. On this basis, a disaster recoverability index is established to measure the resilience of bridge structures. The proposed classification standard of bridge disaster recoverability is given, which provides a new way of thinking and reference for bridge disaster prevention and disaster prevention design in our country at present.
