A rigid foundation slab that moves as a single unit with the soil, minimizing damage from differential movement.

The central thesis of Chen’s work revolves around the concept of the (or Zone of Seasonal Moisture Variation). Chen argues that the failure of foundations on expansive soils is rarely due to a lack of bearing capacity (shear failure), but rather due to differential heave caused by moisture changes in this specific zone.

Chen established specific criteria for evaluating expansion potential (low, medium, high, or very high) based on physical properties like Atterberg limits , plasticity index, and colloid content. Foundation Design Strategies: The text advocates for several techniques to combat heave: Deep Foundations:
