Preload removal based on excess pore-water pressure

Proceedings of the Institution of Civil Engineers - Ground Improvement, 1997
When applying a preload embankment to prevent residual primary consolidation settlement of a soft clay layer, it is necessary to decide, based on data from on-site measurements, if the preload has been left long enough to allow removal. One method of making this decision is to estimate the value of excess pore-water pressure. The authors observed from

Study on Dissipation of Excess Pore Water Pressure of Clay

Applied Mechanics and Materials, 2012
Dissipation of excess pore water pressure of saturation clay was discussed in the paper. Monotonic loading, unloading-reloading, and creep tests of one dimensional compression were performed to study the orderliness of dissipation of excess pore water pressure. In the drained consolidated tests, strain rate was changed step by step to check the effects

Excess Pore Pressures During Undrained Clay Creep

Canadian Geotechnical Journal, 1973
The objective of this presentation is to examine experimentally how the excess pore-water pressure is related to the mechanism for undrained creep of San Francisco Bay mud. The results are discussed in the context of creep mechanisms previously suggested in the literature and based on laboratory testing.It is found that shear strains occurring during ...

Influence of Excess Pore Pressure Development on Inertial Pile Response

2023
The behavior of piles in submerged and liquefiable sandy soils under earthquake loads attracted attention of researchers since 1980s. In this study, behavior of soil surrounding piles in such soils was investigated. In the study, response of the piles under inertial loads was considered, and it was assumed that the soil was in passive terms of during ...

Initial Excess Pore Pressure in Soils

Journal of the Geotechnical Engineering Division, 1980
The purpose of this note is to present a Newmark type of influence chart to estimate the instantaneous excess pore pressure in deep, homogeneous soils due to surface vertical loads of any arbitrary but finite shape. It is concluded that assumption of Boussinesq type distribution for instantaneous excess pore pressure could result in gross ...

Correlation between excess pore water pressure and seismic waves

Journal of the Chinese Institute of Engineers, 1993
Abstract On the site of the Large Scale Seismic Test at Lotung, Taiwan, an in‐situ pore water pressure measurement program has been ongoing since 1986. Its purpose is to measure the changes in ground pore water pressure due to earthquake excitations. During the July 30 (M = 6.2) and the November 15 (M = 7.0), 1986 earthquakes, which occurred in Eastern

Excess Pore Pressure Measurement and Monitoring for Offshore Instability Problems

Offshore Technology Conference, 2007
Abstract In situ pore pressure is one of the fundamental parameters required for assessing the strength and stability of geomaterials. In particular, identification of pore pressure regimes is necessary in geohazards studies. Offshore geological processes such as rapid sedimentation, minor slides, erosion, and fluid

Excess pore pressure in Mississippi delta front sediments: Initial report

Marine Geotechnology, 1976
Abstract In September 1975, a differential piezometer probe was successfully implanted in the soft seafloor sediments of Block 28, South Pass, Mississippi Delta. The probe sensor is located approximately 6.4 m below the mudline in a water depth of 19 m, and has essentially continuously monitored excess pore pressure (the difference between sediment ...
