摘要

To obtain an empirical model of the relationship between slope stability and rainfall in Tiemagou, Bomi County, Tibet Autonomous Region, China, linear regression was used to analyze the rainfall and three-dimensional displacement data collected by a GNSS landslide displacement monitoring system in July. The results show that there is a linear relationship between the rainfall and the three-dimensional displacement and that the amount of rainfall is closely related to the slope stability. An empirical model linking the rainfall and slope stability was then developed by analyzing the data acquired by the landslide monitoring system. This model can reflect the slope stability well and is suitable for application to slopes in areas where the geological conditions are similar to those at Tianmagou.
