Coupled analyses of seepage and deformation of expansive soil slopes during rainfall

Abstract:

The development of the pore pressure and deformation of a canal slope excavated in unsaturated expansive soil in Zaoyang City during artificial rainfalls is simulated by use of the simplified consolidation theory of unsaturated soil. The computed results are qualitatively agreeable to the observed data.

Key words: side slopes of canal,rain infiltration,unsaturated soil,consolidation theory,numerical simulation
