Abstract

A shear box for testing cyclic shear characteristics of a rock mass discontinuity includes: an upper shear box including an upper semi-open cavity composed of an upper left side plate, an upper right side plate, an upper front side plate, an upper rear side plate and an upper top plate; and a lower shear box including a lower semi-open cavity composed of a lower left side plate, a lower right side plate, a lower front side plate, a lower rear side plate and a lower bottom plate; the upper shear box includes at least one first adjusting device for adjusting a space size of the upper semi-open cavity; the lower shear box includes at least one second adjusting device for adjusting a space size of the lower semi-open cavity; and the upper shear box and the lower shear box are placed opposite to each other.
