Experimental Study on the Variation Law of Excess Pore Water Pressure at the Bottom of the Foundation Pit for Excavation

open access: yesAdvances in Materials Science and Engineering, 2020
The excavation unloading of deep foundation pits in soft soil areas often produces negative excess pore water pressure. The rebound deformation of soil on the excavation surface of the foundation pit can be predicted reliably through the accurate ...

Criteria for rapid sliding I.: a review of Vaiont case [PDF]

open access: yes, 2010
Vaiont slide has been represented by a model of two interacting evolutive wedges. Mass conservation during the motion implies that the upper wedge transfers mass to the lower one through an internal shearing plane.

Influence of Sample Preparation and Processing Procedures on the Thermal Diffusivity of MgO‐C Refractories

open access: yesAdvanced Engineering Materials, EarlyView.
The thermal diffusivity of MgO‐C refractories is highly sensitive to sample preparation and processing procedures. In this article, the effects of coking sequence, machining conditions, structural inhomogeneity, and graphite coating application on measurements using laser flash apparatus are systematically investigated.

VARIATION OF PORE WATER PRESSURE IN OVER-CONSOLIDATED CLAY UNDER CYCLIC LOADING: EXPERIMENTAL INVESTIGATION

open access: yesInternational Journal for Computational Civil and Structural Engineering
Under cyclic loading, the cyclical effect of external load during loading time will result in multiple rearrangement of soil particles, and thus causing the particles to arrange more closely together than un static loading.

Reduction of Oxide Inclusions During the High‐Frequency Welding of Steel via a Nonthermal Ar/H2 Plasma Jet

open access: yesAdvanced Engineering Materials, EarlyView.
High‐frequency (HF) welding of steel is limited by oxide inclusions that degrade weld quality. This study demonstrates, for the first time, the integration of a nonthermal Ar/H2 dielectric barrier discharge (DBD) plasma jet into HF welding. Local plasma treatment provides effective shielding and in‐situ oxide reduction, resulting in markedly fewer and ...

Excess pore pressure behavior and evolution in deep coalbed methane reservoirs

open access: yesInternational Journal of Mining Science and Technology
Deep coalbed methane (DCBM), an unconventional gas reservoir, has undergone significant advancements in recent years, sparking a growing interest in assessing pore pressure dynamics within these reservoirs.

CO2 injection into submarine sediments: disturbing news for methane-rich hydrates [PDF]

open access: yes, 2011
The production of natural gas via injection of fossil-fuel derived CO2 into submarine gas hydrate reservoirs can be an example of tapping a hydrocarbon energy source in a CO2-neutral manner.

Handbook of Establishing and Maintaining Oxygen‐Free Atmospheres

open access: yesAdvanced Engineering Materials, EarlyView.
This study presents a practical framework for creating oxygen‐free atmospheres at ambient pressure using silane‐doped inert gases. The results show that ultra‐low oxygen levels and strongly reduced water content can be achieved through controlled silane dosing, drying systems, and sensor monitoring.

Physical Modeling of Reinforced Soil Retaining Walls Under Dynamic Loading Using Shaking Table Experiments

open access: yesInfrastructures
This study investigates the seismic response of reinforced soil retaining walls through reduced-scale 1 g shaking table experiments, with particular emphasis on deformation behavior and pore water pressure generation in saturated sandy soils.

Initial Distribution of Average Excess Pore Water Pressure Due to a Trapezoidal Load

open access: yesSoils and Foundations, 1974
A numerical integration procedure is used to evaluate the equations which give the initial distribution of excess pore water pressure in a subsoil due to a trapezoidal surface load, such as a highway embankment, and a series of curves are provided for a broad range of geometrical variations.
