Walking and tilting-sliding simulation test device with variable active fault dip angle and working method

Abstract

The invention discloses a walking and tilt-slip simulation test device with a variable active fault dip angle and a working method.According to the test device, a walking-slip model box is pushed to move horizontally through a walking-slip pushing device, a settlement platform is controlled to incline through an electric cylinder, and a tilt-slip model box is pushed to move on the settlement platform through a tilt-slip counterforce device; an overlying load pressurizing device is additionally arranged on the upper portion of the strike-slip model box and the upper portion of the tilt-slip model box, high ground stress borne by a tunnel in a fault can be simulated, tunnel damage forms under different tilt-angle faults can be simulated, and more working conditions can be designed compared with an existing experimental model box. According to the invention, strike-slip fault movement and tilt-slip fault movement can be realized, and strike-slip and tilt-slip fault movement can also be carried out; the fault inclination angle can be changed, and experiments under various working conditions can be carried out; according to the model box, the dislocation belt is used for dislocation, the model box better fits the actual condition of fault movement compared with a model box which only conducts dislocation face dislocation in the past, and the application prospect is very wide.

Description

technical field [0001] The invention belongs to the field of test devices, and in particular relates to a walking and dip-slip simulation test device and a working method of a variable active fault dip angle. Background technique [0002] my country's geological conditions are complex, active faults are widely distributed, and more and more traffic projects are being carried out, especially large and long tunnels. Therefore, many tunnels inevitably pass through active mountain faults. When the fault is dislocated, it will often cause damage to the tunnel, such as lining cracking, tunnel internal collapse, tunnel fracture, etc., especially under the action of earthquake damage, the damage is even greater. For the damage research of tunnels crossing active faults, many scholars at home and abroad have summarized three research methods—theoretical analysis, numerical simulation, and model experiments. Among them, model experiment is the most intuitive, reliable and accurate me...
