8. under the simulation fault movement as in any of the one of claim 1-6, the assay device of tunnel seismic response is adopted
Test method, it is characterised in that: described test method is used for simulating reversed fault, comprises the following steps:
(1) according to the Analysis of Field Geotechnical Parameters in testing program and similar proportion, the test soil body is carried out rational proportion and put by the test soil body
In model test box and be positioned at lifting drawer away from the side of chamber door, open the chamber door of model test box so that operation；
(2) the deployed soil body is laid in the bottom of model test box to tunnel model floor height, in the length of model test box
Tunnel model is put in degree direction, one end that one end of tunnel model is relative with chamber door on model test box, tunnel model
The other end, near the inner surface of lifting drawer, installs the detection device including foil gauge, covers the top soil body；
(3) angle of inclination adjusting guide rail makes it consistent with the inclination angle in fault rupture face, adjusts the loading speed of hydraulic jack
And make it upwardly lift drawer, lifting drawer moving process remains original vertical state, dish on simulation reversed fault
Moving upward, stop and fixing lifting drawer after reaching to set displacement, now tunnel model is by fault movement shear action；
(4) spring matrix and spring installing plate are installed in the lower section of bearing soleplate, during according to the changing of the relative positions scope of lifting drawer
Spring installing plate is carried out padded, prevents lifting drawer and move down excessive；
(5) drawer to be lifted is stable under the support of spring matrix, the jack base outside disassembly model proof box and hydraulic pressure
Jack, the chamber door closing model test box makes whole proof box close, and vibration table is started working, failure under earthquake action, spring
Matrix lifts the high vibration of drawer and plays cushioning effect when vibration table works to support, and tunnel model is in changing of the relative positions face part
By shear action repeatedly, and spring chess matrix analogue Wall rock resistance, it is achieved the reversed fault simulation of this assay device.
