... changes in excess pore-water pressure caused by induced mechanical and thermal stresses in the surrounding sediment. Pore pressure increases can cause time-dependent changes in the physical and mechanical properties of the sediment and thus affect the integrity of the sediment's “isolation” capacity...

... into the disposal of high-level radioactive wastes and in other areas for different applications. Over 40 deployments have been made using pop-up pore-pressure instruments (PUPPIs) over the past few years to depths of up to 6 m below the seabed in water depths greater than 5000 m. PUPPIs have a resolution as low...

... Experiment (ISHTE). The sediment at the Pacific test site 1100 km north of Oahu, Hawaii, is an illitic clay. Insertion-induced excess pore pressures were found to agree well with those predicted by models. Several aspects of the induced excess pressure dissipation were evaluated including the effects...

... data confirm that cyclic shear strain is the fundamental parameter governing pore pressure buildup, because strain-controlled tests essentially eliminate the influence of specimen fabric and sample disturbance. Also, the results indicate that the cyclic triaxial test can be used to model cyclic simple...

... A theoretical study of pore-pressure distributions in drained, constant strainrate triaxial tests, an outgrowth and extension of earlier work by Gibson, Bishop, and Henkel, has been done to determine the experimental conditions under which pore-pressure gradients, and hence, effective stress...
