A dissolution-diffusion sliding model for soft rock grains with hydro-mechanical effect

Journal of Rock Mechanics and Geotechnical Engineering, 2018
The deformation and failure of soft rock affected by hydro-mechanical (HM) effect are one of the most concerns in geotechnical engineering, which are basically attributed to the grain sliding of soft rock.

Dynamic model for water-rock interface of softening of soft rock and its evolution law

Yantu gongcheng xuebao, 2022
The softening mechanism of soft rock is essentially the deterioration of microstructure caused by change of water-rock interface. The research on the water-rock interface is of great importance.

Preparation Method of Similar Materials for the Progressive Disintegration of Red-Bedded Soft Rock Based on Diagenesis Simulation

Buildings, 2023
Solid waste formed during the excavation of soft red stratum rock is often encountered in engineering practice. However, its reuse has been limited because it often shows a gradual degradation mechanism during water–rock interactions.

Research on Deformation Monitoring of Invert Uplifts in Soft Rock Tunnels Based on 3D Laser Scanning

Applied Sciences, 2023
The soft surrounding rock in tunnels has the characteristics of low strength, easy softening after soaking, and poor self-stability, which makes the inverted arch structure in soft rock tunnels prone to uplift deformations.
