With the continuous expansion of the range and scale of human activities, especially human engineering activities, destructive landslide events in China have significantly increased, and the harmfulness brought to society has gradually increased. Research on landslide prediction is always a theoretical and technical problem that experts and scholars in various subject fields of engineering geology, rock mechanics and the like in the world pay great attention to. The research work starts with how to predict and forecast the landslide and avoid various losses caused by the landslide.

However, the occurrence time, scale, development trend and the like of the landslide can be successfully predicted only by monitoring the landslide with enough precision and timely and accurately acquiring the feature information of the landslide, so that the purpose of disaster prevention and reduction is truly achieved. Therefore, basic data acquisition and monitoring in the first step play a fundamental guarantee and foundation role in the subsequent work.

According to different monitoring objects, landslide monitoring can be divided into four categories: displacement monitoring (ground absolute/relative/deep displacement monitoring), physical field monitoring (stress/strain/acoustic emission monitoring), underground water monitoring (underground water level, pore water pressure and soil moisture monitoring) and external induced factor monitoring (earthquake, rainfall and freeze-thaw monitoring).
