摘要
复反应法是用来分析地震动力作用下岩土体动力性质的有限元方法之一。这种方法的主要特点是引入复模量概念，使材料的阻尼比与频率无关，这样能更好的模拟岩土体的动力性能。本文结合在建的某公路深埋隧道，分析了隧址区山体的地震动作用特点。
Complex analysis is an effective finite element method to simulate the dynamic response of rock soil mass to earthquake. By using complex modulus to format the stiffness matrix, the damping ratio is irrelevant to the frequency, then the properties of rockmass can be simulated rationally. In this paper, a case about a mountain tunnel along Chuanzhang Highway is used to analysis the characteristics of dynamic response of rock soil mass to earthquake, and the correlation of the tunnel depth with the seismic intensity is also discussed.
