Similar simulation test device with controllable load and adjustable dimension

Abstract

The invention relates to a similar simulation test device with the controllable load and adjustable dimension. The test device comprises a device frame, a left baffle, a right loading plate, an upperloading plate, a front baffle and a rear baffle. The left baffle is vertically arranged at the inner side of a left standing column of the device frame in a front-back direction; and the lower end ofthe left baffle penetrates a base of the device frame downwardly and can slide up and down relative to the base. The right loading plate is vertically disposed at the inner side of a right standing column of the device frame in a front-back direction; and a horizontal loading device in transmission connection with the right loading plate is installed at the right standing column. The upper loadingplate is horizontally disposed at the position, being close to a top beam, in the device frame in a left-right direction. A moving mechanism is arranged on the device frame and is in transmission connection with the upper loading plate. A vertical loading device is arranged at the top beam. The front baffle and the rear baffle are respectively installed at the front and rear sides of the device frame in an up-down sliding manner. The device has the following advantages: controllable loading of the similar model in vertical and horizontal directions can be realized; the pouring area size of the similar model can be adjusted; and the operation becomes convenient.

Description

technical field [0001] The invention belongs to the technical field of similar simulation test devices, in particular to a similar simulation test device with controllable loading and adjustable size. Background technique [0002] The similarity simulation test is based on the similarity theory, and the similarity model is constructed by preparing rock-like materials with similar mechanical properties to the engineering rock mass. The load is applied to the similar model by the similar simulation test device to simulate the actual stress environment of the rock mass engineering, and the deformation and failure characteristics of the engineering body are studied in combination with the excavation model and other work. At the same time, the sizes of similar models corresponding to engineering bodies of different sizes are different, resulting in the need for similar test devices of different sizes for the test. [0003] In traditional technology, such as "loading device for s...

Problems solved by technology

These methods cannot apply controllable vertical and horizontal loads to similar models, and the size of the device model is fixed, which is difficult to meet the research needs of complex engineering conditions

[0004] In addition, in some existing technologies, the technology of applying vertical and horizontal loads to similar models through hydraulic jacks is disclosed, such as "a loadable similar simulation test device and its use method (CN201610002446.7)". Apply vertical and horizontal loads to similar models, but the pouring model of the device is complex, and the problem of fixed size of the loadable model of the device is not solved

[0005] In addition, there are some existing technologies that disclose the technology of three-dimensional controllable loading of large-scale similar models, such as "a large-scale three-dimensional physical model test with high-stiffness prestressed loading frame structure CN201810106804.8" patent technology realizes large-scale similar models Three-dimensional controllable loading, but the device is suitable for models of fixed size, and the manufacturing cost of the device is expensive, so it is difficult to popularize and apply
