| 英文摘要 | Deformation in a rock mass in deeply buried fault zones induced by active fault slip significantly affects the operational safety of long linear tunnels passing through it. The creep slip movement, deep in situ stress condition, and rock mass characteristics of the active fault zone are the significant factors in exploring the mechanical response of deep-buried fault-cross tunnels. This paper used a new experimental setup to simulate fault creep slip, fully considering the above research factors. A three-dimensional load function, slip mechanism with variable angles, and flexible loading device with airbags and air springs were installed in this test system. We developed new types of modeling material, and tests were conducted to obtain the deformation and failure characteristics of tunnel lining subjected to creep slip. Also, the feasibility and reliability of the setup were verified. The test results imply that the tunnel failure was distributed within 3.5 to 4.0 times the tunnel diameter. The tunnel lining failure is strongly dependent on the S-shaped displacement mode and its hill-shaped displacement gradient mode. This study helps to provide a design basis for a tunnel structure crossing deeply buried active faults. |
