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 ...

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

Excess Pore Water Pressure along the Friction Sleeve of a Piezocone Penetrating in Clay: Numerical Study

, 2020
Excess pore water pressure (EPWP) measurements taken at different positions on a penetrating piezocone into a clayey soil are believed to play an important role in correlating to its chara...

Pore Pressure Generation of Gravelly Soils in Constant Volume Cyclic Simple Shear

Journal of Geotechnical and Geoenvironmental Engineering, 2023
: Excess pore pressure generation of uniform gravel and gravel-sand mixtures was evaluated in this study. Comparisons were made with existing relationships for pore pressure generation of sands and show that gravel and gravel-sand mixtures can exhibit ...

Precise Model for Predicting Excess Pore-Water Pressure of Layered Soils Induced by Thermal-Mechanical Loads

Journal of engineering mechanics, 2019
This paper proposes a precise model to investigate the time-dependent response of excess pore-water pressure in stratified saturated soil induced by coupling effects from temperature and me...

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 Pressures Around Underground Structures Following Earthquake Induced Liquefaction

International Journal of Geotechnical Earthquake Engineering, 2012
Underground structures located in liquefiable soil deposits are susceptible to floatation following an earthquake event due to their lower unit weight relative to the surrounding saturated soil. This inherent buoyancy may cause lightweight structures to float when the soil liquefies.

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 ...

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 ...

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 ...
