Abstract: A method for monitoring stability of a high-steep slope in a high-altitude cold region is provided. The method includes the following steps: step 1, geological survey: investigating and analyzing a geological structure, soil and rock types, a rock property, topographic mapping, and a historical disaster record of a slope to be monitored; step 2, terrain measurement: monitoring an elevation, a gradient, an inclination angle, and a crack of the slope to be monitored; step 3, geological environment monitoring: monitoring a temperature, a humidity, a groundwater level, and a rainfall of the slope; step 4, remote sensing monitoring: using a remote sensing (RS) technology to obtain a remote sensing image of the slope and monitor displacement changes within the slope; and step 5, intelligent warning: setting a monitoring threshold based on slope stability, and issuing a warning when monitored data reaches the monitoring threshold.
