In this study the vertical swelling pressure in disturbed expansive soil was evaluated under constant-volume hydration swelling tests. The volume change during inundation was observed under two conditions: constant vertical stress at inundation and constant volume. A swelling stress-strain relationship model of compacted expansive soil is established under a one-dimensional axial load, which is related to the properties of the soil and can be used to predict the swelling stress of compacted soil with high density or strain under a specific axial load. This study can help to predict the swelling stress and strain of compacted expansive rock.
