Description

Technical Field

[0001] The invention relates to the technical field of a multifunctional slope stability simulation experiment, and in particular to a multifunctional indoor slope physical simulation device under rainfall conditions. Background Art

[0002] Rainfall is one of the main factors contributing to slope instability, as it can cause changes in the location of potential sliding surfaces. Because slopes are complex accumulations, studying the impact of rainfall on slope stability requires comprehensive consideration of multiple factors, including rainfall intensity, duration, and the physical properties of the slope itself. Furthermore, field studies examining the effects of natural rainfall on slope stability are inherently uncertain in terms of time and duration. Artificial rainfall simulation can effectively control the timing, intensity, and distribution of rainfall.

[0003] Current indoor research on slope stability under rainfall conditions primarily relies on indoor simulation experiments, using rainfall systems to deliver artificial rainfall to slope models. However, most slope models have fixed angles and limited applicability. This also ignores the impact of rainwater evaporation, a key variable on model stability, resulting in a waste of water resources when using rainfall systems to simulate artificial rainfall. Furthermore, some currently developed models are complex to operate, have poor device functionality, and suffer from low reusability. Summary of the Invention
