A pseudo-static analysis method is presented to calculate sensitivity of lining internal forces due to earthquake action considering influential factors such as vertical and horizontal seismic loads, pore pressure build up, and rock pressure. The method is applied to a engineering project also. Results show that: the sensitivity has no relation to the value of the influential factors, but to the shape of the tunnel and coefficient of lateral pressure; the sensitivity is in the direct proportion to the coefficient of lateral pressure, which implies that shallow buried tunnels are more sensitive to seismic load; horizontal seismic load is the most sensitive factor of lining forces and some most sensitive positions are given; water pore pressure is good to lining's internal forces. |
