Hydro-Mechanical Assessment of Rainfall-Induced Tunnel–Pile–Slope Interaction through Numerical and Field Investigations of Deformation and Stability

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...

Numerical Assessment of Flood-Induced Deformation and Stability of MSE Walls

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...

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...

THE STABILITY OF SOIL-ROCK MIXTURE SLOPES UNDER COMBINED EFFECTS OF RAINFALL AND TUNNEL EXCAVATION

Because of their heterogeneous composition, soil-rock mixture (SRM) slopes respond strongly to both rainfall infiltration and tunnel excavation. In the model test, heavy rainfall was applied while two tunnels were excavated, and water content, deformation, and earth pressure were monitored continuously. Settlement accu...

Investigation of the failure mechanism and reinforcement control effect of cut slopes under climate change

Under climate change, the increasing frequency of extreme rainfall events has made soil cut slopes more prone to progressive instability. Understanding their deformation–failure mechanisms and reinforcement effects is therefore of engineering significance. However, previous studies have mainly focused on overall stabil...
