摘要

研究高速公路隧道基于双地震动强度参数的易损性及概率地震经济损失，对震前抗震防灾及震后急救修复意义重大。本文建立了高速公路隧道设计基准期内概率地震经济损失评估框架，引入双地震动强度参数，采用增量动力法进行了易损性分析，得到的易损性曲面与经验易损性曲线进行对比，验证了本文所建模型及易损性曲面的合理性。以此为基础，评估了隧道设计基准期内的概率地震经济损失。结果表明：建立的基于双地震动强度参数下的易损性曲面能更准确地反映结构损伤，在高速公路隧道设计基准期内，轻微损伤造成的概率地震经济损失占比最大，中等损伤次之。本文提出的隧道概率地震经济损失评估框架可对高速公路隧道地震经济损失评估提供参考。

Abstract

The research on the fragility analysis and probabilistic seismic economic loss of highway tunnel based on double intensity measures is significant for pre-earthquake earthquake prevention and post-earthquake emergency repair. In this paper, the evaluation framework of probabilistic seismic economic loss in the whole life cycle of highway tunnel is established, the double intensity measures are introduced, the fragility analysis is carried out by incremental dynamic analysis method. The comparison between the analytical fragility surface and the empirical fragility curve verifies the rationality of the model and the fragility surface established in this paper. On this basis, the probabilistic seismic economic losses in the whole life cycle of tunnel are evaluated. The results show that the fragility surface based on double intensity measures can reflect the structural damage more accurately, and the probabilistic economic loss caused by slight damage is the largest during the whole life cycle of highway tunnel, followed by moderate damage. The framework of tunnel probabilistic seismic economic loss assessment proposed in this paper can provide reference for highway tunnel seismic economic loss assessment.
