The invention discloses an apparatus for simulating the fracture of a strike-slip fault. The apparatus comprises a loading device, a supporting device, a testing device, an auxiliary device and a fault model device; the fracturing speed of the fault is measured through a sound emission sensor in the testing device; the load of a jack is changed; the fracturing speed and evolution process of the fault can be monitored; acceleration data generated by different parts of the fault can be measured through a two-way acceleration sensor in the testing device; the acceleration data are converted intospeed data through an analog circuit; pulse data are extracted from the speed data; and therefore, the pulse characteristics and distribution laws of seismic records under different fault fracturing speeds can be obtained.
