Expanded soils are widely distributed in Xinjiang, China, so roadbeds will inevitably pass through the areas of the expansive soil during road construction. While Xinjiang belongs to the seasonal frozen region, subjected to a freeze?thaw cycle, mud pumpi...

This work presents a comprehensive coupled thermal-hydro-mechanical model to explore the frost heave mechanism of the concrete-lined canal under a freeze?thaw environment. Unlike previous models that regard concrete as a homogeneous material, this model ...

Destructuring settlements due to frost heave during the structures? exploitation are often not taken into account at the designing stage, although they are indirectly related to the bearing capacity of the soils. The objective of this research was analyz...

Short-term surge in the spring thaw of liquid water is one of the root causes of structural performance of subgrade weakening seasonal frozen region. Ice and water phase transition changed the strength and deformation of subgrade. Especially in wet soil ...
