is used to evaluate the pore-water pressure
Sassa, "Seismic loading impacts on excess pore-water pressure
maintain landslide triggered flow-slides," Earth Surface Processes and Landforms, vol.
where u is excess pore-water pressure
and z is the height beneath the upper boundary.
VW piezometers are used to monitor pore-water pressure
in the borehole.
The dissipation of pore-water pressure
in the embankment is largely influenced by the permeability and the storage characteristic of the embankment materials.
SLOPE/W (Part of a Geo studio 2007) can effectively dissect both simple and complex problems for a variety of slip surface shapes pore-water pressure
conditions soil properties analysis methods and loading conditions.
Therefore, during the study of rainfall effects on landslide, the amount of water infiltration in a rainfall process has important influences on negative pore-water pressure
of the soil and thus on landslide stability, which requires further studies.
Seed and Booker (1977) approach for pore-water pressure
generation and dissipation is applied, with some modifications for evaluating the densification effect of GPs, incorporating modifications in coefficients of volume change and permeability, to the analysis of columnar gravel drains under a variety of earthquake conditions.
AND WATER TABLE VARIATION DURING EARTHQUAKE SIMULATIONS.
where u and [bar.u] are the excess pore-water pressure
and average excess pore-water pressure
, respectively; [c.sub.r] and [c.sub.v] are the coefficients of consolidation in the radial and vertical directions, respectively; r is the distance from the origin of the vertical drain in the radial direction; z is the distance from the surface of the foundation in the vertical direction; and t is the time.
Rezaur, "Effect of antecedent rainfall on pore-water pressure
distribution characteristics in residual soil slopes under tropical rainfall," Hydrological Processes, vol.
Several scholars have studied the development law of pore-water pressure
under cyclic loading, the most famous among which was finished by Seed and Idriss .
