Abstract
An experimental system for simulating creep and stick-slip dislocations of a fault in a tunnel structure includes a box structure, a supporting device and a fault dislocation loading system. A friction effect layer, a first surrounding rock layer, a tunnel structure model, a second surrounding rock layer and an overburden pressure layer are sequentially arranged in the box structure from bottom to top. The bottom of the box structure is provided with a through hole. A plate assembly is provided on the through hole, and includes a first guide plate, a second guide plate and a loading plate. Inner sides of the first guide plate and the second guide plate are respectively provided with a first slide rail and a second slide rail. The loading plate moves along the first slide rail and the second slide rail under the action of the fault dislocation loading system.
