Influence of the thermal effect on quasi-static shear characteristics of calcareous soil: an experimental study

open access: yesGeoenvironmental Disasters, 2022
In principle, the mechanical properties of soil particles are irreversibly changed after particles are subjected to heating. Accordingly, this study performed ring-shear tests on calcareous sand samples subjected to high temperatures to qualitatively ...

Shear mechanical response and deformation failure of F-type socket joint in a rectangular pipe jacking tunnel under different geologic conditions

open access: yesScientific Reports, 2023
The shear mechanical properties of F-type socket joints in rectangular pipe jacking tunnels are currently unknown. To investigate the shear mechanical response and deformation failure of the F-type socket joint in rectangular pipe jacking tunnels under ...

A new shear rheological model for a soft interlayer with varying water content

open access: yesWater Science and Engineering, 2018
The rheological behavior of a soft interlayer is critical to understanding slope stability, which is closely related to the water content of the soft interlayer. This study used the soft interlayer of the Permian Maokou Formation in Southwest China as an

Experimental and Numerical Studies on the Impact Energy Absorption of Cutting Shear Rings

open access: yesApplied Sciences, 2023
To improve the passive safety of the collision process, we designed a kind of energy absorption device based on cutting shear rings (CSR). It can be installed in a limited space, overcoming the characteristic of traditional energy absorption devices that

Shear behavior of bedding fault material on the basal layer of DGB landslide

open access: yesScientific Reports, 2023
Daguangbao (DGB) Landslide (12 × 108 m3) is the largest landslide triggered by the 2008 Ms8.0 Wenchuan Earthquake, in which basal shear failure develops on an interlayer fault at 400 m deep under the ground.

Normalisation of shear test data for rate-independent compressible fabrics [PDF]

open access: yes, 2007
This article describes a method of using both picture frame (PF) and bias extension (BE) tests together to characterize accurately the trellis shearing resistance of engineering fabrics under low in-plane tension conditions.

Development and Performance Evaluation of a Bevameter for Measuring Soil Strength

open access: yesSensors, 2021
The driving performance of an off-road vehicle is closely related to soil strength. A bevameter is used to measure the soil strength, and it usually consists of two independent devices: a pressure–sinkage test device and a shear test device. However, its
