The stability of pipeline slopes is vital for maintaining a secure and reliable energy supply. However, real-time field monitoring and research in extreme cold environments remain insufficient. In permafrost regions, energy pipeline slope stability is affected by multiple factors, including rainfall infiltration, freeze-thaw cycles, groundwater level fluctuations, seismic activity, and human interventions. Existing monitoring techniques, such as slope deformation measurements, hydrogeological surveys, and geophysical methods (e.g., self-potential and microseismic monitoring), typically assess landslide risks from a singular perspective. However, a comprehensive, multi-field quantification of slope failure processes is still lacking.

This paper focuses on the northern section of the China-Russia Eastern Gas Pipeline, integrating real-time multi-geophysical monitoring to assess slope hydrogeological conditions. Combined with geotechnical analysis, we characterize variations in rock and soil strength and evaluate slope stability. The findings contribute to the development of multi-field monitoring and early warning strategies, enhancing the safe operation of energy pipelines in extreme cold regions.
