Theoretical and experimental study investigates shear strength in soil-rock mixtures, suggesting enhanced mechanical behavior due to rock blocks.

This research aims to understand the multiscale coupling shear strength of soil-rock mixtures (S-RM) and how rock blocks influence this strength.
Proposed a multiscale soil–rock cell element model to analyze S-RM.
Conducted three groups of in situ large-scale direct shear tests on S-RM samples with varying rock block contents.
Calibrated microscale parameters of the model using experimental data.
Rock blocks significantly affect the mechanical behavior of S-RM.
Trans-scale coordinated deformation induces strain gradients at the mesoscale.
Increased energy release at the macroscale due to rock blocks enhances shear strength.

Feng et al. (2026) studied this question.
