Problems solved by technology

[0007] However, in the three-dimensional model test platform studied above, the loading devices are all rigid loading plates, and the applied loads are not evenly distributed, which cannot simulate uniformly distributed flexible loads. Therefore, the test results deviate greatly from the actual situation
As a result, the test results cannot provide a theoretical basis for related engineering designs

Abstract

The invention discloses a uniform load distribution supercharging device, and a three-dimensional side slope destruction model testing apparatus and method, belonging to the technical field of testing strength characteristics of solid materials by using mechanical stress. The supercharging device comprises a flat plate, a force application unit and a supercharging mechanism, wherein the force application unit is used for applying acting force with an action point on the flat plate, the flat plate directly contacts an object bearing the acting force, and the supercharging mechanism is used for increasing the magnitude of force capable of being applied outwards by the bearing object. The testing apparatus is realized based on the supercharging device. The testing method is implemented based on the testing apparatus. The supercharging device can realize uniform load distribution, and when the magnitude of the force capable of being applied outwards by the bearing object is increased through the supercharging mechanism, increased load is also uniformly distributed. By adopting the testing apparatus and method, a testing result in a loading part destruction process, acquired after testing, is closer to a real scene, and a more accurate theoretical basis can be provided for related engineering design.

Description

technical field [0001] The invention relates to the technical field of using mechanical stress to test the strength characteristics of solid materials, in particular to a uniformly distributed load booster device, a three-dimensional slope model test load device and a method. Background technique [0002] Force is one of the basic physical quantities, because all aspects of the effect of force can be attributed to size, direction, and point of action. Therefore, the size, direction, and point of action of force are the three elements of force. In scientific research, for the sake of convenience, the research object is often abstract, concrete and visualized. Force is the action of an object on an object, and has action modes such as pushing, pulling, lifting, pressing, attracting, and repelling. When studying, we can regard the force acting on the object as concentrated at one point, which is the point of action of the force. Two forces with the same magnitude and directio...
