Comprehensive geotechnical engineering test platform for complex slope geological model tests

Abstract

The invention discloses a comprehensive geotechnical engineering test platform for complex slope geological model tests. The comprehensive geotechnical engineering test platform comprises a test platform framework, an angle control device, a loading system and a loading control device, wherein the test platform framework is used for forming a complex slope geological model, the angle control device is used for controlling test platform framework angle change, the loading system is used for perform pressure loading on the complex slope geological model and the loading control device is used for controlling the loading system, and a combined retaining plate is laid on the test platform framework. The comprehensive geotechnical engineering test platform has the advantages that a plurality of sub-frames can form a single linear slide structural face, a double-broken-line slide structural face and two intersecting slide structural faces with inclination-angle-opposite included angles, the inclination angles of the formed structural faces can be adjusted optionally, the deformation and fracture researches of complex single structural face slide rock slip mass, double-broken-line structural face slide rock slip mass and wedge-shaped rock slip mass with or without reinforcing protecting structures can be achieved, and precise adjustment of test platform framework angle change and loading pressure during the tests can be achieved.

Description

Technical field [0001] The invention belongs to the technical field of geological model test equipment, and relates to a test platform device that can be used to study the deformation and failure of slope geological model and the deformation and stress of protective structure, and specifically relates to a comprehensive geotechnical engineering test platform for complex slope geological model test. Background technique [0002] Slopes generally include natural slopes and artificial slopes. Due to the combination of internal and external adverse effects, slopes often evolve into sudden landslides and geological disasters, often causing traffic interruptions and large economic and personnel casualties. Therefore, scientific research on slopes has always been the focus of research by experts and scholars in the field of geotechnical engineering. For a long time, in view of the disadvantages of actual on-site slope scientific research, such as high cost, hindering construction and po...

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
