The utility model provides a shear apparatus loading device, which comprises a counter-force plate arranged at the top of a counter-force frame; the loading system comprises a hydraulic jack, and thebottom of the hydraulic jack is connected with the counter-force plate through a constant-rigidity compression spring; the loading plate is used for applying normal load to a shearing box of the shearing instrument; and a piston rod of the hydraulic jack applies pressure to the loading plate. Pressure can be applied to the shear box under the condition of maintaining constant rigidity, and the actual situation that the pressure of a rock-soil body on a structure belongs to the force application under the condition of constant rigidity can be accurately simulated, so that the simulation of an indoor test on the actual situation more conforms to an objective law. 本实用新型提供一种剪切仪加载装置，包括：反力板，其设于反力架的顶部；加载系统，所述加载系统包括液压千斤顶，所述液压千斤顶的底部通过恒刚度压缩弹簧与所述反力板连接；用以对剪切仪的剪切盒施加法向荷载的加载板，所述液压千斤顶的活塞杆向所述加载板施加压力。可以实现对剪切盒在维持恒刚度条件下施加压力，可以准确的模拟岩土
