Problems solved by technology

If the tunnel structure is not improved and optimized, the tunnel passing through the fault will have lining fracture and spalling, resulting in large deflection deformation, and even the tunnel collapses completely, leading to collapse and damage in severe cases

Abstract

The invention discloses a tunnel lining structure of self-monitoring adjustment suitable for crossing active faults and a construction method thereof. The tunnel lining structure comprises a groutingreinforcement layer, an energy dissipation damping layer, a prefabricated tunnel lining structure and a steel arch frame, wherein the grouting reinforcement layer is used for realizing excavation stability when construction is conducted on a surrounding rock excavation face of a fault crushing belt; the energy dissipation damping layer covers the bottom of the grouting reinforcement layer; the prefabricated tunnel lining structure is arranged above the energy dissipation damping layer and is formed by hinging a plurality of sections; the steel arch frame is arranged above the prefabricated tunnel lining structure, the two ends of the steel arch frame are installed at the tops of the steel plates at the two ends of the energy dissipation damping layer correspondingly, and a certain distanceis reserved between the steel arch frame and the grouting reinforcement layer; and a monitoring reinforcing instrument is arranged on the inner wall of a grouting reinforcement region, the monitoringreinforcing instrument comprises a monitoring device and a spray head, wherein the monitoring device is installed on the inner wall of the grouting reinforcement region, the spray head is installed on the monitoring device, the spray head is connected with a grouting pump, and the grouting pump is connected with a slurry source.

Description
