Dynamic soil tunnel interaction in layered half space for incident plane SH waves
The dynamic soil tunnel interaction is studied by indirect boundary element method (IBEM) using the model of a rigid tunnel in layered half space, which is simplified to a single soil layer on elastic bedrock, subjected to incident plane SH waves. The accuracy of the results is verified through comparison with the analytical solution. It is shown that soil tunnel interaction in layered half space is larger than that in homogeneous half space and this interaction mechanism is essentially different from that of soil foundation superstructure interaction.
