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

Abstract

The invention relates to a similar simulation test device with controllable loading and adjustable size, comprising a device frame, a left baffle, a right loading plate, an upper loading plate, a front baffle and a rear baffle; It is vertically arranged inside the left column of the device frame, and its lower end penetrates the base of the device frame downwards, and can slide up and down relative to the base; the right loading plate is vertically arranged inside the right column of the device frame along the front and rear direction, A horizontal loading device connected to the right loading plate is installed on the right column; the upper loading plate is horizontally arranged in the device frame near the top beam along the left and right directions, and the device frame is equipped with a moving mechanism, which is connected with the upper loading plate. The plate is connected by transmission; the top beam is equipped with a vertical loading device; the front baffle and the rear baffle are respectively installed on the front and rear sides of the device frame by sliding up and down. Advantages: It can realize the controllable vertical and horizontal loading of similar models, the size of the pouring area of ​​similar models can be adjusted, and the operation is 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...
