The invention discloses a test apparatus and method for simulating the power reaction of a bedding slope. The test apparatus comprises a normal loading device, a tangential loading device, a shearing box, a measuring device, a hydraulic device and a numerical control device, the normal loading device comprises a normal oil cylinder and a normal load sensor, and the tangential loading device comprises a tangential oil cylinder and a tangential load sensor; the shearing box comprises an upper shearing box and a lower shearing box, the upper shearing box only moves vertically, and the lower shearing box only moves horizontally; and the measuring device comprises a normal deformation sensor and a tangential deformation sensor. Normal load and tangential load are applied to an overlying model and an underlying model which have different dimensions and shapes by means of a rock direct shearing test system in order to simulate the power reaction of the bedding slope under the action of earthquake, explosion and other loads, so different research demands are met.
Description
technical field [0001] The invention relates to the field of laboratory experiments of rock mass dynamics, in particular to a test method for simulating the dynamic response of a forward slope. Background technique [0002] A slope is a geological body with a lateral free surface on the crustal surface, consisting of a slope crest, a slope surface, a slope foot, and a slope body within a certain depth below it. Slopes are divided into rock slopes, soil slopes and rock-soil mixed slopes according to stratum lithology. Among them, rock slopes are divided into layered structure slopes, massive structure slopes and network structure slopes according to the rock structure; layered structure slopes can be further divided into forward slopes , reverse slopes, tangential slopes, and vertical slopes. The rock stratum inclination of the slope is the same as the slope aspect, and its stability problem is one of the classic problems in the field of engineering geology and rock mechani...
