摘要
在地震灾害发生后,铁路隧道会受到不同程度的破坏,如何对震后损失情况进行定性定量评估成为一项非常重要的工作。本文从铁路隧道结构构造角度出发,采用分层加权综合评估法对铁路隧道的不同构造及常见震害形式权重值进行了计算、分析,研究表明:在铁路隧道震后灾害损失定量评估时,准确合理的权重值,可以实现震后单座隧道以及整个震区所有隧道的震害损失评估,也可以为震害修缮或重建决策提供依据。
Railway tunnel will be affected by damages of different degree after the earthquake disaster, how to assess the earthquake losses qualitatively and quantitatively becomes a very important work. From the perspective of different structures of railway tunnel, the weighted value of railway tunnel with different structures and common forms of earthquake damage was calculated and analyzed in this paper by hierarchical weighted comprehensive assessment method. It showes that when the loss quantitative assessment was performed after the earthquake disaster, the accurate and reasonable weight value can realize the earthquake disaster loss assessment for the single-seat tunnel and all of the tunnel in the entire region, and also can provide decision-making basis for the earthquake damage repair or reconstruction.
