Abstract

The invention discloses a supporting structure of a active fault crossing tunnel and a tunnel lining structure, and relates to the technical field of tunnel engineering. The supporting structure comprises a first support and a second support, the first support comprises a first pipeline arranged in the longitudinal direction of the tunnel and a second pipeline arranged outside the first pipeline in a sleeved, and concrete is filled between the first pipeline and the second pipeline, the second support comprises a plurality of first anchor rods radially arranged in the radial direction of the tunnel, one end of each first anchor rod is fixedly connected with the second pipeline, the other end of each first anchor rod extends to external surrounding rock, and a cavity is preset between the second pipeline and an excavation contour line of the tunnel in the radial direction of the tunnel. The supporting structure of the active fault crossing tunnel and the tunnel lining structure have good fault creep diastrophism damage resistance, and damage to the whole tunnel caused by fault creep can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering, in particular to a support structure and a tunnel lining structure for a tunnel spanning an active fault. Background technique [0002] my country is located between the Eurasian plate, the Indian Ocean plate, and the Pacific Rim plate. Affected by plate movements, active faults of various sizes are widely distributed. With the rapid development of economy and science and technology, my country has vigorously built tunnels. When encountering active faults, it is mainly to avoid them. However, due to the constraints of line selection, a large number of tunnels still inevitably have to cross active faults. The continuous and slow sliding of rock mass along both sides of the fault plane is called fault creep, and the sudden slip of rock mass along both sides of the fault plane is called fault stick-slip. Compared with fault stick-slip, fault creep does not directly generate earthquakes. ...
