Abstract Crushed rock revetment (CRR) has been widely implemented to mitigate the geothermal disturbance from the embankment construction and global warming. The cooling effect and air convective mode of the traditional CRR (TCRR) and a new designed solar−shading CRR (SSCRR) were comparatively studied based on a developed and verified heat and mass transfer model. The results indicate that TCRR used as a protecting measure cannot eliminate the geothermal disturbance in warm permafrost regions, b...

Abstract Alterations in the permafrost due to a warming climate increases the risk of permafrost thawing, accelerates carbon release, lowers super-permafrost groundwater, strengthens desertification, and destroys infrastructure. The permafrost temperature in six boreholes up to 40 m depth was measured from 2003 to 2015 along the Qinghai–Tibet Railway. Results showed an increase in the permafrost temperature, with an average of 0.14 °C decade−1 at 10 m depth. The deep permafrost showed significan...

Abstract Climate warming causes profound consequences on permafrost distribution throughout the high-latitude regions of the globe. Xing'an permafrost in China is the southernmost part of high-latitude permafrost and is constantly changing. However, understanding on this change process of permafrost is limited. On the basis of digital elevation model (DEM) data, meteorological station, survey data and the meteorological forcing dataset in the northern northeast area in China, we calculated the m...

Observational data on permafrost and active layer soil hydrothermal processes are extremely limited in the upper reaches of the Heihe River (URHHR) in Qilian Mountains. This lack acts as a bottleneck, restricting the research on the hydrological functions of different landscapes and the hydrological effects of the changes in the permafrost and active layer in the alpine permafrost regions of the Heihe River Basin. The active layer seasonal freeze-thaw processes and the soil hydrothermal dynamics...

Abstract Duct-ventilated railway embankment (DVE) is relatively effective at preserving underlying permafrost under the current climatic conditions. To increase its capacity to adapt to climate warming, a ripped-rock revetment was added to the DVE. To evaluate the effectiveness in cooling of different embankment treatments, long-term in-situ soil temperature data were collected from eight experimental embankment sections along the Qinghai–Xizang Railway in the Beiluhe region between 2002 and 201...

Abstract An embankment with heat insulation can only retard a rise in temperature or the thawing of permafrost, and the thermal stability of the embankment cannot be maintained under global warming conditions. Therefore, strengthening measures are required to ensure embankment stability. Based on in-situ observational data from the Qinghai–Xizang Railway in Beiluhe, variations in the thermal regime under a thermally insulated embankment after the implementation of strengthening measures were ana...
