Abstract
An integrated observation dataset of the hydrological-thermal deformation in permafrost slopes and engineering infrastructure in the Qinghai-Tibet Engineering Corridor: Across the Qinghai-Tibet Plateau (QTP) there is a narrow engineering corridor with widely distributed slopes, called the Qinghai-Tibet Engineering Corridor (QTEC), where a variety of important infrastructures are concentrated. These facilities are transportation routes for people, materials, energy, etc., from mainland China to Tibet. From Golmud to Lhasa, the engineering corridor covers 632 km of permafrost containing the densely occurring Qinghai-Tibet Railway and Highway as well as power/communication towers. Slope failure in permafrost regions, caused by permafrost degradation, ground ice melting, etc., affects the engineering construction and permafrost environments in the QTEC. We implement a variety of sensors to monitor the hydrological-thermal deformation between permafrost slopes and permafrost engineering projects in the corridor. In addition to soil temperature and moisture sensors, the global navigation satellite system (GNSS), terrestrial laser scanning (TLS), and unmanned aerial vehicles (UAVs) were adopted to monitor the spatial distribution and changes in thermal deformation. An integrated dataset of hydrological-thermal deformation in permafrost engineering and slopes in the QTEC from the 1950s to 2020, including meteorological and ground observations, TLS point cloud data, and RGB and thermal infrared (TIR) images, can be of great value for estimating the hydrological-thermal impact and stability between engineering and slopes under the influence of climate change and engineering disturbance. The dataset and code were uploaded to the Zenodo repository.

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,
evaluate the potential hazards of long-term stability and safety operation of the engineering infrastructure and slopes, and provide data support for the safety range and layout of the proposed permafrost engineering infrastructure.
