Appraising the potential of calcium sulfoaluminate cement-based grouts in simulated permafrost environments

Frontiers of Structural and Civil Engineering 2023, Volume 17, Issue 5, Pages 722-731 doi: 10.1007/s11709-023-0950-5

Abstract: study is to appraise the potential of calcium sulfoaluminate (CSA) cement-based grouts in simulated permafrostfabricated using CSA cement can develop rapidly in cold environments, thus rendering them promising for permafrost

Full-scale site evaluation of ventilation expressway embankments underlain by warm permafrost along the

Frontiers of Structural and Civil Engineering 2023, Volume 17, Issue 7, Pages 1047-1059 doi: 10.1007/s11709-023-0034-6

Abstract: and combination of these, were adopted for the construction of the Gonghe−Yushu Expressway in warm permafroststrong scale effect of a wide embankment, the crushed-rock embankment (CRE) was warming up and the permafrostslab and CRE and ventilated ducts embankment can effectively decrease the ground temperature and raise permafrostThese findings would provide a reference for construction of expressway embankments in permafrost regions

Permafrost Degradation Threatening the Qinghai−Xizang Railway

Qingbai Wu,Wei Ma,Yuanming Lai,Guodong Cheng,

Engineering doi: 10.1016/j.eng.2024.01.023

Abstract: The thawing and warming of ice-rich permafrost present a considerable threat to the long-term stabilityIn this review, we explore the extent of the observed permafrost degradation and embankment damage underThe ice-rich permafrost beneath the embankment presents a substantial threat to the thermal–mechanicalstability of the embankment due to the permafrost’s accelerated and amplified degradation.stability of permafrost.
