technical field

The utility model belongs to the technical field of landslide test boxes, in particular to a landslide simulation test box.

Background technique

Landslide is a common geological disaster in my country, which is characterized by strong danger, large distribution range and high frequency of occurrence. Rainfall and earthquakes are important factors that induce landslides. The intensity, duration and frequency of rainfall will directly affect shallow landslides; earthquakes will destroy the structure of the complete rock and soil of the slope, turning the low-risk landslide into a disaster-sensitive area. Due to the characteristics of fast speed and long distance, it is difficult to achieve rapid warning or forecast of landslide disasters. It is necessary to conduct simulation tests on the disasters in advance according to the on-site conditions and specify corresponding preventive measures.

The existing landslide model test box device usually only considers the influence of a single factor on the landslide when simulating the landslide disaster, such as only the influence of rainfall on the landslide, or only the influence of the earthquake on the landslide. In addition, when setting up the matching rainfall simulation device, the simulation device only considers the amount of rainfall and other factors, and cannot actually simulate the more real rainfall in nature, resulting in a deviation between the final test results and the actual situation.
