摘　　要：从"5.12汶川大地震"及世界范围的工程结构物震害情况看,在强震条件下,隧道工程震害依然较突出,合适的抗震设计方法是工程界共同面临的课题。当前进行抗震设计计算的拟静力方法主要有地震系数法与反应位移法,文章结合工程实例阐述了两者的基本原理。通过改变埋深、地震烈度和偏压等参数,对隧道受力情况进行了计算,对比分析两种方法的计算结果,就其适用性进行了探讨和研究。It is evidenced by the ＂5.12 Wenchuan earthquake＂ and worldwide earthquakes that tunnels are still subject to severe damage in intense earthquakes, so the appropriate aseismic design method is a common and essential issue in tunnel engineering. Currently,the two major quasi-static calculation methods of aseismic design are earthquake coefficient method and seismic deformation method. The basic principles of both are described,and the internal forces of a shield tunnel in soft soil are calculated with various specifications of depth of the ground,earthquake intensity and other parameters. The results from the two methods are compared and analyzed to discuss the adaptability of these two methods.
