PORE PRESSURES NEAR MOVING UNDERWATER SLOPE

Pore pressures near a moving boundary of a saturated soil mass are calculated and compared with tests. For a more realistic approximation of the stress-strain behavior of soil, a dilatancy effect has been introduced that is based upon Rowe's stress-dilatancy relation and the assumption of a linear relationship between the principal stress ratio and the major principal strain. The field equations for the problem have been transformed to account for the traveling boundary. A psuedo three-dimensional consolidation theory is used to describe the fulid-soil skeleton interaction. The results of the computations were compared with pore-pressure measurements and showed reasonable agreement if dilatancy was taken into account. /ASCE/
