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 ...

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

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 ...

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 ...

A New Technique for Reduction of Excess Pore Pressures During Pile Driving

Canadian Geotechnical Journal, 1974
A new technique is described whereby excess pore pressures induced during pile driving in soft, varved silts and clays were economically reduced to a safe level. The technique was applied to piles at a bridge site south of Stockholm, Sweden, where a small slide had occurred during pile driving.

Effect of “Matching” on the Prediction of Excess Pore Water Pressure in Plane Strain Analyses

2018
Consolidation analyses of embankments are often conducted on the assumption of the plane strain condition. This poses a problem if the effects of vertical drains (used for accelerating consolidation) are to be modelled. The conditions for the consolidation around vertical drains are close to axial symmetry. “Matching” procedure (Hird et al.

Consolidation Characteristics And Excess Pore Water Pressures Of Mississippi Delta Sediments

Offshore Technology Conference, 1978
ABSTRACT The majority of sediment instability problems in the Mississippi delta area of the Gulf of Mexico are related to weak, under consolidated sediments that are subjected to movement by both gravity forces and bottom pressures from storm waves.

Identifying Consolidation Coefficient: Linear Excess Pore-Water Pressure

Journal of Geotechnical and Geoenvironmental Engineering, 2008
Diagnostic curve methods are developed for simultaneously identifying consolidation coefficient, final settlement, and ratio of top and bottom excess pore-water pressures from observed settlements, in the case of linear excess pore-water pressure. Simple equations are also proposed for estimating consolidation coefficient and final settlement.

Evaluation of excess pore pressures around piles driven into clayey soils

2015
In many cases, excess pore pressures generated during pile driving into clayey soils lead to a decrease in the effective stresses around the pile, thus facilitating the driving process. The dissipation of these pore pressures can be considered as the main mechanism that explains the occurrence of gains in load capacity of piles with time, known as set ...
