中文摘要：
为了对隧道震害的影响因素进行分析，文章搜集了汶川地震中4座破坏较为严重的隧道震害资料进行统计分析，并通过ANSYS软件建模进行了计算验证。统计分析和数值模拟结果表明，隧道震害的几个主要影响因素包括地震参数（地震波峰值加速度）、围岩级别、隧道埋深、与隧道相交的断层、隧道洞身的特殊结构部位等。其中地震波峰值加速度越大、围岩级别越低或当隧道通过断层时，隧道衬砌破坏程度越严重；隧道埋深越大隧道震害程度越小；隧道洞身特殊结构段处容易发生应力集中，引起震害程度加重。
英文摘要：
In order to analyze the influential factors of tunnel damages induced by an earthquake, the relative data of four tunnels seriously affected by the Wenchuan earthquake were collected and analyzed statistically, as well as calculated and verified through ANSYS software modeling. The results show that the main influential factors include the earthquake parameters （earthquake wave peak acceleration）, the surrounding rock grade, overburden, faults intersecting with the tunnel, special tunnel structures, and so on. The damage to the lining is more serious if the earthquake wave peak acceleration is high, the rock mass is of a low grade, or the tunnel passes through faults. The damage to the lining is inversely proportional to the overburden depth. Stress easily concentrates at the special structures of a tunnel, resulting in worse damage.
