Abstract

The invention relates to a loadable device for similarity simulation test and a use method thereof. The technical scheme adopted by the invention is characterized in that an upper cross beam (1), a lower cross beam (10), a left vertical column (11) and a right vertical column (4) are connected into a rectangular frame; two angle steels (5) are symmetrically fixed on inner-side wing plates of the left vertical column (11) and the right vertical column (4), and a front-side baffle plate (9) and a rear-side baffle plate (8) are correspondingly fixed on the angle steels (5) at the front side and the rear side of the rectangular frame. A first hydraulic jack (2) is vertically fixed on the lower plane of the upper cross beam (1), and an upper pressurizing plate (3) is fixed at the extending end of the first hydraulic jack (2); a second hydraulic jack (6) is horizontally fixed on the inner side surface of the right vertical column (4), and a right pressurizing plate (7) is fixed at the extending end of the second hydraulic jack (6); and a first roller (12) and a second roller (13) are respectively arranged at the left end of the upper pressurizing plate (3) and the lower end of the right pressurizing plate (7). The loadable device has the characteristics of simple structure, low cost, strong operability and capability of realizing controllable loading, and is applicable to study of similarity simulation test for underground rock engineering.

Description

technical field [0001] The invention belongs to a similar simulation test device. In particular, it relates to a loadable similar simulation test device and an application method thereof. Background technique [0002] With the continuous development of social production, the problems raised by underground geotechnical engineering have become increasingly complex and cumbersome. Whether it is mineral resource development or underground transportation construction, it is difficult to obtain accurate analytical solutions purely by mathematical methods. People have to use experimental methods to explore the regularity of complex phenomena that cannot be studied by theoretical knowledge. At the same time, due to the huge size of underground geotechnical engineering, it is generally irreproducible, so the similar simulation test is a very effective research method. At present, a simple plane two-dimensional similar simulation test device is widely used. Although this type of dev...
