Shrinkage and Strength Behavior of Highly Plastic Clay Improved by Brick Dust

Journal of Engineering, 2020
Highly plastic soils exhibit unfavorited properties upon saturation, which produce different defects in engineering structures. Attempts were made by researchers to proffer solutions to these defects by experimenting in practical ways.

High Temperature Friction and Strength of Felsite and Basalt: Implications for Supercritical EGS at Krafla, Iceland

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract One promising potential site for extracting supercritical geothermal fluids is the Krafla volcano, Iceland, into which a borehole was drilled very close to a shallow rhyolite magma chamber at about 2 km depth. Besides the technical challenge to drill in this setting, the extreme temperature conditions of T > 900°C close to the magma body may ...

Study on GMZ bentonite-sand mixture by undrained triaxial tests

E3S Web of Conferences, 2016
It is particularly necessary to study the deformation, strength and the changes of pore water pressure of bentonite-based buffer/backfill materials under the undrained condition.

Hydro‐Mechanical Controls on Swarm Recurrence on the Westernmost Gofar Transform Fault, East Pacific Rise

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Swarms are microearthquake clusters governed by aseismic deformation, fluid migration, and stress changes, but the underlying mechanisms for their recurrence remain elusive. In 2008, abundant swarms were observed on the westernmost Gofar transform fault.

Parameter variability of undrained shear strength and strain using a database of reconstituted soil tests [PDF]

, 2020
During construction, the mobilisation of undrained shear strength must be limited to avoid soil failure. Soil strains must be controlled to avoid compromising structural serviceability.

Support pressure for circular tunnels in two layered undrained clay

Journal of Rock Mechanics and Geotechnical Engineering, 2020
To estimate the required support pressure for stability of circular tunnels in two layered clay under undrained condition, numerical solutions are developed by performing finite element lower bound limit analysis in conjunction with second-order cone ...

Research of undrained shear strength of till fine soils (moraine) /

, 2019
The undrained soil strength is specific to fine soils or to sands with a lot of fines. It is very important characteristic and the evaluation of accurate value is significant step. The undrained soil shear strength can be estimated directly in laboratory

Comparative analysis of saturated–unsaturated shear strength under undrained loading: Experimental validation and ANN prediction of clayey soils

AIP Advances
Geotechnical designs and analyses of earth structures and foundations exclusively involve the assessment and consideration of unsaturated soil shear strength. The laboratory testing equipment and methods for predicting the unsaturated soil shear strength
