| 英文摘要 | Dynamic perturbation is a significant factor to induce dynamic stress concentrations and vibration velocities in underground engineering. The investigation presented in this paper focuses on the transient responses around a deep-buried composite-lined tunnel with imperfect interface between intermediate liner and rock mass. Based on the integral transform and numerical inversion of Laplace transformation, the time-history variations, temporal and spatial evolutions for stress and velocity around the tunnel are explored theoretically. The results indicate that the incident and shadow sidewalls are characterized by tensile stress concentration around the inner boundary, while the roof and floor are compressive stress concentration areas. The radial and hoop elastic coefficients for the interface have an important influence on the dynamic responses around the tunnel and small elastic coefficients lead to more complicated dynamic responses. The results can provide theoretical basis for the support of underground lined tunnels. |
