Abstract
The invention relates to a landslide model test system, comprising a landslide model box, a model slope body as a test object is arranged in the landslide model box, and a loading mechanism is arranged on the model slope body; the loading mechanism includes an upper surface placed on the model slope body and a The flexible airbag between the upper cover plates of the landslide model box, the flexible airbag is connected to the pressure supply unit to change the internal pressure of the flexible airbag through the pressure supply unit and apply the load required for the test to the model slope body through the expansion of the flexible airbag; the model slope There are several lateral inclinometers embedded in the body. The invention can greatly increase the range of slope heights that can simulate landslides through pressure adjustment, and realizes flexible loading of model slope loads through the structure of flexible airbags. When the model slope becomes unstable and deformed, the flexible airbags will generate corresponding in real time Deformation, to ensure that the load value applied to the top surface of the model slope is constant, so as to simulate the gravity load more realistically and effectively.
Description
technical field [0001] The invention belongs to the technical field of measuring and testing ground materials by physical methods, and in particular relates to a landslide model test system. Background technique [0002] Landslides can lead to disasters such as road damage, house collapse, formation of barrier lakes, etc., resulting in huge loss of life and property, and are one of the most important geological disasters. [0003] Loading landslide model test is an effective method to study the mechanism of landslides. There are also relevant researches in the prior art, such as CN103308663A, CN106885894A, CN107490668A, CN108279296A, CN207675761U, CN108918828A, CN109507390A, which provide perfect information on individual components such as landslide model test box structure, landslide surface structure, and freeze-thaw landslides; For example, CN1584542A, CN109208656A, CN207488288U, CN107807223A, CN105842418A, CN105510556A, and CN102331489A provide research information on ...
