Rainfall-Related Shear-Zone Weakening and Stability Degradation of a Reactivated Loess–Carbonaceous Slate Landslide

This study investigates the deformation evolution and stability degradation of a rainfall-reactivated loess–carbonaceous slate landslide in Luoda Town, Gansu Province, China. Field investigation, borehole logging, water-content-controlled direct shear tests, GNSS monitoring, rainfall analysis, and FLAC3D modeling were...

Moisture-induced degradation of clay-bearing sandstone

Clay-bearing sandstones used in the construction of historic monuments, churches, and castles are highly susceptible to contour scaling, which manifests as fractures parallel to the exposed facades. Repeated wetting–drying cycles accelerate material degradation through stiffness reduction and hygric deformation induced...

Progressive Deformation Mechanism and Stability Analysis of a High-Fill Expansive Soil Slope

Background: To elucidate the hydraulic response, progressive deformation, and wetting-induced swelling effects of high-fill expansive soil slopes throughout the rainfall–cessation process. Methods: A high-fill expansive soil slope in Jianshui, Yunnan Province, China, was selected as the study case. A three-dimensional...

Hydro-mechanical behaviour of a geosynthetic reinforced soil wall with fine-grained backfill under rainfall conditions

The use of fine-grained soils as backfill in geosynthetic-reinforced soil walls has increased worldwide, despite concerns regarding climate-induced intense rainfalls. This study investigates the hydraulic–mechanical behaviour of a large-scale segmental reinforced soil wall constructed with a fine- grained backfill and...

Stability Failure Characteristics of Hanzhong Granitic Residual Soil Slopes Under Coupled Effects of Rainfall Intensity and Slope Inclination

Hanzhong granitic residual soil exhibits a pronounced rainfall-sensitive response, but the evolution of hydraulic participation and failure pathways under different rainfall intensities and slope inclinations remains insufficiently understood. Physical model tests and coupled Geo-Studio simulations were conducted under...

Instability Mechanism of a Soil–Rock Binary-Structure Slope Under Rainfall Conditions

Rainfall-induced instability of highway slopes with a soil–rock binary structure may be strongly influenced by the hydraulic barrier effect of low-permeability shale. This study investigated the right-side slope along the D-ramp section from DK0+230 to DK0+660 at Deze Interchange on the Zhanhui Expressway, China. A two...
