Embodiment Construction

[0028] The implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0029] as attached figure 1 As shown, a multifunctional geotechnical model test box includes an outer frame 1. The outer frame is welded by steel plates and section steel. The dimensions are 1850mm×1660mm×420mm in height, length and width. The dimensions are 1200mm x 800mm x 300mm in height, length, and width. Both sides of the packing tube are steel plates, and the front and rear sides are plexiglass; there is a loading beam 2 on the top of the outer frame, and a pressure test device is installed on the loading beam. Multifunctional geotechnical model test box Ground anchor bolts 18 are provided on the base plate 7 to be fixed to the ground, and a displacement control device is provided below the stuffing tube.

[0030] The pressurization test device includes a jack 19 connected to the loading beam 2, and a force measuring ring 20 connected to t...

Abstract

The invention discloses a multifunctional geotechnical model test chamber device adopting photogrammetric technology. The multifunctional geotechnical model test chamber device comprises a model test chamber body, a loading and testing part, a movable pile baffle, a downward-moving control part, a displacement testing system and the like. The whole-filed displacement is measured by using the photogrammetric technology. The soil arch effect demonstration of 20 different pile spacing ratios, the pile-supported embankment filler particle soil arch effect and a compound foundation cushion layer effect simulation test under the rigid foundation can be realized. Meanwhile, the geotechnical model test chamber device can also carry out simulation such as stress and deformation simulation of buried pipes, slope deformation, excavation of foundation pits, stress and deformation of an enclosing structure and the like by using the test chamber.

Description

technical field [0001] The invention relates to the research field of a geotechnical model test device, in particular to a multifunctional geotechnical model test box. Background technique [0002] At present, in the research on the deformation, stability and failure process of geotechnical engineering, due to the slow reaction process, the effect of direct observation in daily research is poor, so most of them currently use model tests. [0003] Model test is a new technology that has been widely studied in the process of geotechnical engineering deformation, stability and failure. Due to the many influencing factors of the geotechnical model, the model is very complex, so the requirements for the geotechnical model are also high. Contents of the invention [0004] The object of the present invention is to provide a geotechnical model test box with accurate measurement, wide application range and low cost. [0005] The present invention is achieved like this: [0006] ...
