Stress in plane depends primarily on the shearing stress distribution state of contact surface between panel and bed course.There is the heart in core wall rockfill dam
Wall earth material and filter material, polytype contact interface such as dam shell material and basement rock.These usual contacts site are that dam body is easily sent out again
The research for the former weak link, thus generation soil particle and structure interface shearing mechanics of making trouble, wherein most widely used instrument
Device is direct shear apparatus, existing boxshear apparatus using placing concrete or other test blocks below shear box, test block be directly placed at bottom plate or
Bottom is provided with the floor of ball, and horizontal pull device is connected with concrete test block, pulls concrete to be in contact face shearing,
But contact of the concrete with bottom plate inevitably produces sliding friction or rolling friction impacts to test accuracy.
Utility model content
The shortcomings that the purpose of this utility model is to solve in the prior art, and propose a kind of boxshear apparatus that is used for and measure
The device of shearing force.
To achieve these goals, the utility model adopts the following technical scheme that：
Two water have been arranged side by side in a kind of device for boxshear apparatus measurement shearing force, including bottom plate, the bottom plate upside
Translation power apparatus, the horizontal power device include tumbler, and tumbler is provided with rotating shaft, rotating shaft outer end connects bearing,
Bearing is fixed on the upside of bottom plate, and the first torque sensor is provided with the rotating shaft between the bearing and tumbler, and first turns round
The second torque sensor is provided between power inductor and bearing, is turned between the second torque sensor and the first torque sensor
Axle.
Preferably, tumbler is rotating machine.
Preferably, the rotating shaft outer axial face between first torque sensor and the second torque sensor sets axle teeth.
The advantages of the utility model：It is simple in construction, it is simple to operate, during direct geared is set with moving tooth plate reduction
Outer friction power, lift the precision of the horizontal shear force of survey.
