Abstract

The invention discloses a slope deformation simulation test device under a rainfall condition. The slope deformation simulation test device comprises a model box body (1), a strip mine slope model (2) and a rainfall simulation device (3), wherein the model box body (1) takes the shape of a cube of which the upper part is opened and at least one of four sides is transparent; the strip mine slope model (2) is arranged inside the model box body (1) and comprises a top platform (201), a slope surface (202), a slope base platform (203) and a water catch basin (204); the rainfall simulation device (3) is mounted above the strip mine slope model (2) and is used for realizing rainfall simulation. By adopting the slope deformation simulation test device, influence on slope deformation from various rainfall conditions can be effectively simulated, and scientific test requirements can be met.

Description

technical field [0001] The invention relates to a slope deformation simulation test device, in particular to a slope deformation simulation test device under rainfall conditions. Background technique [0002] Among all kinds of natural disasters, landslides are one of the geological disasters that cause the most serious casualties and economic losses. Therefore, discovering the mechanism of landslides and realizing the effective prevention of landslide accidents has been one of the major topics that scientific research personnel have devoted themselves to studying for a long time. After research, rainfall was identified as the main trigger of the landslide. On the one hand, rainfall will increase the hydrostatic pressure inside the open-pit mine slope, and on the other hand, it will reduce the strength parameters of rock and soil, which will lead to landslides on slopes such as mountains and cause accidents. Like mountains, slopes in open-pit mines are prone to landslides ...
