An analytical method is presented for evaluating the stresses in linings of tunnels due to strong earthquake. Under the condition of plane strain, the method considers the factors leading to linings failure of tunnels, such as pore water pressure buildup, horizontal and vertical ground motion. From a standard site-response analysis, using the vertically propagating shear-wave model, the distribution of horizontal free-field ground displacement with depth is obtained. Three-axis test or experimental formula is employed to identify the main parameters of pore pressure development. Vertical ground motion is proportional to the maximum earth's surface vertical acceleration directly. From the numerical results calculated, it can be seen that vertical motion and pore water pressure buildup play significant roles in seismic analysis of tunnels. The proposed method, with above factors concerned, is mainly applied to evaluate stresses including moment, axial and hoop forces in lining.
