The light simulation mechanism is used to illuminate the box to simulate sunlight, and can add water to the box or drain water from the box to simulate changes in reservoir water level. The test device can couple multiple physical field influencing factors of landslides and perform tests. It can arrange landslide simulation tests under single factor, double factor and multiple factor influences according to test requirements, simulate the coupling relationship between physical fields in different environments, and is beneficial to qualitative and quantitative research and analysis of landslide evolution mechanism.
