Regional Screening of Thermal Protection Requirements for Transport Embankments in the Continuous Permafrost Zone of Russia

Analysis of Temperature Regime Changes in an Embankment within the Permafrost Zone of Yakutia (Based on Numerical Modeling in COMSOL Multiphysics)

Objective: to perform a numerical analysis of the temperature regime changes in a railway embankment and its multilayered foundation, situated in the continuous permafrost zone of Central Yakutia, considering "water-ice" phase transitions and seasonal fluctuations of climatic factors. Methods: the study employs the fin...

Strengthening Low-Volume Road Design Through the Integration of Climatic Hydrology

Ensuring the Stability of Subgrade in Permafrost Areas Using the Example of Amur Oblast

Objective: to conduct a comparative assessment of the effectiveness of rock riprap and pile foundations for ensuring subgrade stability in permafrost areas of Amur Oblast. Methods: assessment of embankment slope stability using the Shakhunyants method (circular cylindrical slip surfaces) in the GEO5 software. Calculati...

Numerical Evaluation of a Mirror-Slope Rockfill Replacement for Embankments in Warm Island Permafrost

Highway embankments in warm island permafrost regions of Northeast China are vulnerable to climate warming and foundation softening. To improve long-term temperature and deformation control, a mirror-slope rockfill layer (MSRL) and corresponding mirror-slope rockfill embankment (MSRE) are proposed by mirroring the emba...

Criterion-based control method for production wells in permafrost regions

The growing number of production wells in permafrost regions calls for enhanced monitoring of thermal impacts on frozen ground. Thawing leads to loss of bearing capacity, wellbore deformation, and cavity formation, resulting in environmental risks, accidents, and economic losses. Consequently, monitoring and control of...

Scenario-based stability analysis of an embankment dam under rapid drawdown conditions

This study presents a comprehensive assessment of the transient slope stability of the Gavoshan embankment dam, located in western Iran, under a range of rapid reservoir drawdown scenarios. The analysis was performed using a sequential seepage–stability framework, in which transient pore pressures were computed in SE...
