This system is mainly used to observe the water content, pore pressure and displacement of the accumulation landslide during the process of precipitation and snowmelt. By arranging meteorological stations at the location of the moraine landslide, the temperature, precipitation and snow cover in the area are observed; displacement, pore pressure and water content sensors are arranged in the deep part to observe the pore pressure and pore pressure in the deep part of the slope in real time during the process of rainfall or ice and snow melting. Changes in water content and generation of slope displacement. Through this series of means, various factors in the sliding process of the landslide in the moraine accumulation layer are fully collected to provide basic data for the study of its initiation mechanism.
