Stress–Strain Strength Characteristics of Undisturbed Granite Residual Soil Considering Different Patterns of Variation of Mean Effective Stress

Applied Sciences, 2021
Granite residual soil is one of the most frequently encountered problem soils in tropical regions, whose mechanical behavior heavily depends on the pattern of variation of mean effective stress (p’) during shearing, which can be classified into three ...

Evolution of cracks in the shear bands of granite residual soil

Journal of Rock Mechanics and Geotechnical Engineering, 2022
The evolution of shear bands and cracks plays an important role in landslides. However, there is no systematic method for classification of the cracks, which can be used to analyze the evolution of cracks in shear bands. In this study, X-ray computed tomography (CT) is used to observe the behavior of granite residual soil during a triaxial shear ...

Characteristics of Gravelly Granite Residual Soil in Bored Pile Design: An In Situ Test in Shenzhen

Advances in Materials Science and Engineering, 2018
Granite residual soil is widely distributed in south China and is treated as a special soil. Its design parameters in rotary drilling bored piles are a matter of debate due to lack of in-situ pile load tests.

Seepage improvement test and analysis of granite residual soil

IOP Conference Series: Earth and Environmental Science, 2021
Abstract The influence of slag powder, cement and bentonite on the permeability coefficient of granite residual soil at different incorporation ratios was analyzed by means of seepage test with variable head. Meanwhile, the permeability coefficient was compared with that of the original granite residual soil.

Critical expansion points: Mechanical signs of surrounding rock instability

Deep Underground Science and Engineering, EarlyView.
This study proposes the Rock Bearing‐Expansion Model (RockBEM) with critical expansion points (CEPs) to quantify post‐peak damage stages in deep‐buried rock masses via plane strain compression test (PSCT). CEP hysteresis&interval ratios reveal bearing performance dynamics and failure severity, advancing mechanistic insights into deep underground rock ...

Maximising trait evenness promotes the recovery of plant species richness in managed grasslands

Ecography, EarlyView.
Land‐use intensification threatens biodiversity, and restoring degraded ecosystems remains challenging due to the difficulty of identifying the rules governing community assembly and dynamics. Investigating the temporal dynamics of trait‐abundance distributions (TADs) along long‐term time series offers a promising approach to disentangle the influence ...
