Abstract

The invention provides a tunnel stability protection and prediction system. The tunnel stability protection and prediction system comprises a tunnel inverted-arch support, shotcrete, an intelligent anchor rod, a data acquisition box, a data transmitting box, and a stress and displacement prediction unit. The intelligent anchor rod comprises an anchor rod body, a displacement sensor, a stress sensor and a data line, wherein the displacement sensor is used for monitoring rock mass deformation. The tunnel inverted-arch support is supported at the bottom end of the tunnel. The intelligent anchor rod is installed in the rock mass of a tunnel wall in a hole-drilling method, is fixed to the tail end in a slurry-grouting mode through the outer side, and is fixed in the primary lining of the tunnelby the shotcrete. The intelligent anchor rod is connected with the data acquisition box through the data line. The data acquisition box is electrically connected with the data transmission box. The data transmission box is wirelessly connected with the stress and displacement prediction unit. A tunnel rock mass deformation prediction method is used for calculating the deformation trend of the rock mass of the tunnel wall. The stability of tunnel rock mass is maintained, deformation condition of rock mass is predicted, and the maintenance of structural stability is ensured.
