A novel physical modeling technique for slope failure caused by strength reduction: comparisons with DEM simulation

Tao Yang et al.

Summary: This study developed a new physical modeling technique to simulate slope failure caused by soil strength reduction, and compared the results with limit equilibrium methods (LEMs) and a discrete element method (DEM) simulation. The new technique used age-softening material obtained by placing a matrix material in a softening solution, and showed promising results in reproducing slope failure.

Characteristics and mechanism of dump landslides under compound loads based on physical model test

Chunhui Cao et al.

Summary: In this study, a physical model test was conducted to understand the morphological evolution, deformation characteristics, and mechanism of high slope dump landslides under compound loads. The test results showed that under the influence of compound loads, the dump experienced settlement, collapse, clastic flows, and landslides. The thawing of the ice-snow layer, uneven settlement, dumping style, particle gradation, self-weight, and external loads were identified as important factors affecting the failure of the dump.

Transparent soil model test of a landslide with umbrella-shaped anchors and different slope angles in response to rapid drawdown

Chang Zhou et al.

Summary: Umbrella-shaped anchors play an important role in stabilizing the water-level fluctuation zone during rapid drawdown, preventing slope sliding and collapse. The stability of the water-level fluctuation zone decreases with increasing slope angle.

Centrifuge modelling of static liquefaction in submarine slopes: scaling law dilemma

Weiyuan Zhang et al.

Summary: This paper investigates the scaling laws for centrifuge modelling of static liquefaction initiation and propagation in submerged slopes. It proposes using root N-fluid and N-fluid to simulate static liquefaction and dynamic events, respectively, based on detailed analysis of hydromechanical processes at the grain scale. Centrifuge tests confirm the applicability of the scaling factors of 1/root N and 1/N for pore fluid viscosity in studying static liquefaction onset and post-failure behavior of submarine slopes.

A physical modeling-based study on the control mechanisms of Negative Poisson's ratio anchor cable on the stratified toppling deformation of anti-inclined slopes

Zhigang Tao et al.

Summary: This study investigates the mechanisms governing instability failure of anti-inclined slopes reinforced with NPR anchor cables, and obtains the evolution process of key parameters through physical model experiments. Furthermore, it proves that NPR anchor cables can be used to monitor the sliding force of anti-inclined slopes, laying a foundation for advanced instability warning technology.

Large-scale physical modelling of static liquefaction in gentle submarine slopes

Arash Maghsoudloo et al.

Summary: Monitoring changes in pore pressure and soil acceleration before and during static liquefaction in submarine slopes can help quantify triggering levels and develop safety margins. Model tests in a large-scale facility showed soil instability can start at gentle slope angles, with shear stress change rate and soil state influencing the onset and propagation of instability. Data obtained could validate numerical models for submarine flow slides in the future.
