Slope failure in permafrost regions caused by permafrost degradation and ground ice melting affects the engineering infrastructure and permafrost environment in the Shanghai-Tibetan engineering corridor. Most of the current studies are based on the interaction between individual engineering projects and permafrost slopes by means of multi-point monitoring,

interpolation or simulation. But the dense layout of the various projects and the fragile and sensitive permafrost slopes in the corridor have rarely been previously studied as a whole. The permafrost slopes and various projects, including Shanghai-Tibet Highway, Shanghai-Tibet Railway, power and communication towers located in the corridor are chosen as the research objects.

N3D terrain change monitoring technology using terrestrial laser scanning and global navigation satellite system. Low-altitude remote sensing technology using unmanned aerial vehicle with visible and thermal infrared sensors and in situ monitoring technology was deployed, combined with image mosaic,

three-dimensional modeling and spatial analysis. This dataset contains both site and space features on both the surface and underground horizons, including the ground hydrothermal state, spatial ground surface temperature, slope deformation and meteorological data, thus establishing a comprehensive monitoring

dataset for the Shanghai-Tibet plateau permafrost slopes and surroundings. The dataset will be of great value to examine the hydrological thermal deformation of permafrost slopes under the influence of climate change and engineering disturbances, as well as to reveal the mutual feedback between the slopes and engineering infrastructure,
