A comprehensive geotechnical engineering test platform for complex slope geological model tests

Abstract

The invention discloses a comprehensive geotechnical engineering test platform for a complex slope geological model test, which comprises a test platform frame for forming a complex slope geological model, an angle control device for controlling the angle transformation of the test platform frame, and a complex slope geological model. A loading system for pressure loading and a loading control device for controlling the loading system, and a combined baffle is laid on the test platform frame. In the present invention, by using multiple sub-frame angle changing devices, multiple sub-frames can be flexibly transformed to form a single linear sliding structure surface, a double broken line sliding structure surface and two intersecting sliding structure surfaces with opposite inclined angles, and the formed structure surface The inclination angle can be adjusted arbitrarily, and it can realize the deformation and failure research of relatively complex single structural plane sliding rock slides, double broken line structural plane sliding rock slides and wedge rock slides with or without reinforced protective structures. During the test, the angle change of the test platform frame and the precise adjustment of the loading pressure.

Description

technical field [0001] The invention belongs to the technical field of geological model test equipment, and relates to a test platform equipment for studying the deformation and failure of a slope geological model and the deformation stress of a protective structure, in particular to a comprehensive geotechnical engineering test platform for complex slope geological model tests. Background technique [0002] Slopes generally include natural slopes and artificial slopes. Due to the combined effects of internal and external factors, slopes often evolve into sudden landslide geological disasters, which often cause traffic interruption and large economic and human casualties. Therefore, the scientific research on slopes has always been the focus of experts and scholars in the field of geotechnical engineering. For a long time, in view of the fact that the actual on-site slope scientific research has defects such as high cost, hindering construction, and poor working conditions, ...

Problems solved by technology

Generally speaking, the main research object of rock slopes is the slide mass that deforms and fails along a structural plane of a certain occurrence or a combination of multiple structural planes of different occurrences. The stable rock mass below the slide mass generally does not need to be the main The research object, while the tests in the above-mentioned patents often need to pour stable rock mass below the sliding surface of the sliding body, which is actually a waste. The structural surface where rock landslides slide may often be a double-broken structural surface or have an opposite angle of inclination Two intersecting sliding surfaces of
