中文摘要：
地震概率易损性模型是一种在地震发生后快速且较准确地估算震害损失的方法。本文基于汶川地震的震害调查资料，将汶川地震中所调查隧道的破坏形式分为14种，根据震害程度将隧道的破坏状态分为轻微破坏、中度破坏、严重破坏和完全损毁4种，为方便模型的建立，将隧道结构分为洞口段、断层破碎段和普通段。统计分析调查资料，可以得到每一类隧道结构发生某一种破坏状态的统计概率，再结合隧道对应每一种破坏状态的破坏比，建立隧道的概率易损性模型。依据本文建立的隧道概率易损性模型可能在今后发生类似地震时快速地估计地震灾害损失。
英文摘要：
The earthquake probability vulnerability model is a method that is used to estimate the loss of earthquake quickly and accurately. Based on the survey data from Wenchuan earthquake, this paper classified the tunnel failure modes into 14 kinds, divided the tunnel seismic damage state into minor, moderate, major and collapse class according to the seismic damage level, and divided the tunnel structure into entrance, fractured and ordinary part. By analyzing the statistical survey material, calculating the probability of every tunnel structure in every tunnel seismic damage state and combining with the ratio of each damage state, this paper established the probability vulnerability model, which can estimate the loss of the similar earthquake quickly in future.
