| Abstract |
Utilizing the unsaturated porous elastic media theory, the study investigates the scattering
of plane P-waves by a single-layer lined tunnel within an unsaturated half-space. The analysis employs
the Fourier–Bessel series expansion for wave functions for this purpose. Through numerical examples, this study analyzes how physical and mechanical parameters like incident wave frequency, angle,
saturation, and burial depth affect the surface displacement amplitude in a single-layer lined tunnel
within an unsaturated soil half-space under P-wave incidence. Results indicate that saturation significantly influences the surface displacement amplitude. The maximum surface displacement amplitude
in the single-layer lined tunnel at low saturation levels exceeds that observed at high soil saturation.
The surface displacement amplitude inside the single-layer lined tunnel and on its left side varies
sharply and remains high across different incident frequencies. Conversely, the surface displacement
amplitude on the right side of the single-layer lined tunnel exhibits a relatively gentle change and is
lower. This variation becomes more pronounced with increasing frequency. At a low wave frequency,
the displacement amplitude of the single-layer lined tunnel decreases with the increase of the burial
depth. When the incident wave frequency is high, the displacement amplitude of the single-layer lined
tunnel exhibits a marked change with burial depth increment. |
