Abstract

A large movable lateral uplifting composite lading slope physical model test apparatus comprises a test framework, a bottom uplifting mechanism, a rear portion loading mechanism and a water level elevating simulation mechanism; the bottom of the front portion of the test frame is hinged to the test site ground surface, the test frame is formed by mutually splicing a front panel at the front portion, at least two vertically-arranged guard boards and a frame baseboard at the bottom portion, and the spacing between adjacent guard boards is adjustable; the bottom uplifting mechanism is arranged below the test frame and is used for driving the rotation of the test frame around the hinge pint at the front portion; and the rear portion loading mechanism comprises a loading steel board, an electro-hydraulic servo loading machine and a counterforce wall, the counterforce wall is arranged behind the test frame, the rear end of the electro-hydraulic servo loading machine is hinged to the counterforce wall, the front end of the electro-hydraulic servo loading machine is connected with the loading steel board, and the rear portion loading mechanism is used for applying action force to a slope physical model in the test frame from the rear end of the test frame. The apparatus is suitable for large-size slope physical models, and can realize the establishment of three-dimensional models better satisfying geometric similarity conditions than real slopes.

Description

Technical field

[0001] The invention belongs to the field of geological disaster model tests, relates to test instruments related to landslide physical model tests, and specifically refers to a large-scale movable lateral lift composite loading landslide physical model test device. Background technique

[0002] my country is a country prone to geological disasters such as landslides, collapses, and mudslides. Among them, landslides and other geological disasters account for a large proportion. In addition, due to the continuous intensification of human engineering activities, landslide geological disasters have become one of the major geological disasters in the world. At present, in order to effectively prevent landslides, scholars at home and abroad are trying to use experimental methods to explore the formation mechanism of landslides. Among them, landslide physical model test is one of the effective methods to study the law of landslide formation. It can be used to verify the...
