In order to study the internal force characteristics of shallow-bias tunnel with a small clear distance in earthquake, a large-scale shaking table slope model test was designed, and the geometric scale was 1 : 10.
In the model test, the Wenchuan (WC) seismic wave was used as the excitation wave.
Then, the three-dimensional numerical model was established by using MIDAS-NX, and the reliability of the numerical model was verified by comparing the acceleration of the test results.
The axial force, bending moment, and shear force of the tunnel cross section and longitudinal direction were calculated by the numerical model under different excitation directions included the horizontal direction (X), the vertical direction (Z), and the horizontal and vertical direction (XZ).
The results show the following.
(1) The internal force of right arch foot of left hole and the left arch foot of right hole is larger than other part of the tunnels because the distance between the two tunnels is smaller and they interact with each other.
(2) The loading direction of single direction loading method is different and the variation trend of tunnel force are different, so the loading direction of seismic wave has a significant influence on the seismic force response of the tunnel.
(3) All of the internal force values of tunnel lining under the seismic wave action in bidirection are larger than those in single direction.
The value is not a simple superposition of two directions and has some coupling effect.
The influence of the vertical seismic wave cannot be ignored in dynamic response research.
These results improve the understanding of the rock slope with small spacing tunnel under seismic action.
