Paper presented at the ISRM International Symposium, November 19–24, 2000
Paper Number: ISRM-IS-2000-508
... ABSTRACT: Grain crushing character of sandy soils plays an important role in excess pore pressure generation behavior during rapid landslide motion. Through ring-shear tests, fundamental studies on grain crushing character and excess pore pressure generation behavior are performed. The drained...

Paper Number: ISRM-IS-2000-078
... ABSTRACT: This paper discusses the experimental findings pertaining to wave-induced liquefaction, flow deformation and particle transport in sand beds. Centrifuge wave testing with viscous scaling was applied to reproducing the build-up of residual pore pressures in sand beds leading up...

Paper Number: ISRM-IS-2000-049
... ABSTRACT: The analysis of wave-induced pore pressure and effective stresses is an important factor in the design of offshore installations. However, to simplify the complicated problem, most previous investigations have ignored the effects of inertia forces. This paper presents an analytical...

... engineering. For example, in oil production from oil reservoirs can lead to decreases in the pore pressure. This depletion results in changes of the effective stresses acting in the reservoir and in the deformation of the reservoir. Recently, the significance of the fluid-solid coupled on the recovery...

... Engineering Research Program (EQEN). The research was conducted using the U.S. Army Centrifuge, located in Vicksburg MS. The centrifuge studies have shown that the generation of excess pore pressure is capped at a level below 100% for vertical effective confining stresses exceeding around 3 atmospheres (atm...
