4D Physics‐Based Pore Pressure Monitoring Using Passive Image Interferometry
Geophysical Research Letters, 2023 This study introduces a technique for four‐dimensional pore pressure monitoring using passive image interferometry. Surface‐wave velocity changes as a function of frequency are directly linked to depth variations of pore pressure changes through ...

Physics-Based Relationship for Pore Pressure and Vertical Stress Monitoring Using Seismic Velocity Variations [PDF]
Remote Sensing, 2021 Previous studies examining the relationship between the groundwater table and seismic velocities have been guided by empirical relationships only. Here, we develop a physics-based model relating fluctuations in groundwater table and pore pressure with ...

The Use of Accurate Pore Pressure Monitoring for Risk Reduction in Tailings Dams. [PDF]
Mine Water Environ, 2021 Simply monitoring movement of the tailings dam wall does not address the cause of tailings dam failures and will therefore never be an effective method to reduce or prevent failures. Monitoring the causes of failures is more effective. The main cause of tailings dam failure is slope instability, which is caused by too much water in the wrong place ...

Insights from in-situ pore pressure monitoring around a wind turbine monopile
Ocean Engineering, 2023 Offshore wind turbine monopiles transfer large bending moments into the soil. Due to the large diameter of the foundation, a significant volume of soil is mobilised to absorb the incoming forces from wind, waves and current. If excess pore pressures are generated during load cycles, the long drainage path length could lead to accumulation of pore ...

A Tensile Strength Apparatus with the Facility to Monitor Negative Pore-Water Pressure [PDF]
Geotechnical Testing Journal, 2018 Abstract This article presents a new testing method for investigating the behavior of clayey geomaterials subjected to a tensile (negative) total stress. The method includes the use of high-capacity tensiometers to measure the pore–water pressure of the test specimen, an aspect which has not been demonstrated in any other direct tensile ...
