Influence of permafrost degradation on piles bearing capacity
Abstract The permafrost zone is one of the main natural systems in the Russian Federation that are exposed to global warming. The temperature of permafrost soils changes, the seasonal thaw zone increases, the process of permafrost degradation is started, influencing the strength properties of the so...
