Slope landslide test apparatus

Abstract

The invention discloses a slope landslide test apparatus which includes a model frame system, an axial loading apparatus, an underground water and rainfall simulating system and a servo control system. The model frame system comprises a loading beam, a counter-force beam, a bearing column, a back wall, side walls and a bottom board, is used for producing a model sample and simulating various test status, and is manufactured by jointing steel structures; the axial loading apparatus is in a structure that a speed reducer drives a ball screw pair, wherein a screw rotating nut moves vertically, and a stress sensor is arranged on a front section of the nut. The servo control system is used for controlling the axial loading apparatus to regulate the force; the underground water and rainfall simulating system is used for simulating an underground water seepage test and a rainfall test, system flow rate controlled by adjusting the pressure of the system. The apparatus can be used for carrying out an indoor similarity simulation test to large-scale slope engineering, thereby tracing, analyzing and researching a dynamic evolution process of slope instability.

Description

technical field [0001] The invention relates to the technical field of side slope engineering tests, in particular to a side slope landslide test device. Background technique [0002] Landslide is a geological phenomenon of slope rock and soil sliding along the normal shear failure surface. With the continuous growth of the world's population, the space for human production and living continues to expand, and engineering activities supported by economic and technical conditions are increasingly Frequent landslides, coupled with the influence of global climate change factors, frequent landslide disasters, many of which are large-scale landslide disasters, causing huge casualties and property losses. So far, landslide disasters have occurred in all areas with human production and living activities . [0003] Mine slope stability is a major problem that my country's open-pit mines, especially deep mining open-pit mines, must face. It is an important research direction in the f...

Problems solved by technology

In the slope instability test in the prior art, the scale-down model is often used to pile up on the horizontal ground in a limited closed space. Due to the boundary conditions after scaling down, especially the gravity effect, the slope landslide phenomenon actually occurs through similarity simulation. There are almost no literature and reports, which greatly limits the understanding and exploration of the failure mechanism of slope engineering instability; at the same time, for traditional landslide test sites, it is usually impossible to achieve different groundwater, precipitation, overlying loads, and slope material compositions at the same time. The landslide simulation under the combined effect of variables leads to large simulation errors and cannot reflect the actual landslide damage
