Mudstone Water Absorption and Strength Degradation Test Results from Physical Model

A laboratory physical model test under artificial rainfall conditions, instrumented with pore-water pressure and earth pressure sensors and terrestrial laser scanning for displacement mapping. The dataset contains results quantifying the water-induced softening of mudstone, including unconfined compressive strength degradation from 4.90 MPa to 0.82 MPa within 3 hours. The data was authored by Chi Li and last updated on 2026-04-30.

Use Cases

• Modeling strength degradation curves based on the power-law increase in water absorption described.
• Analyzing the temporal evolution of pore-water pressure based on its described three-stage pattern.
• Validating displacement precursors for early warning based on the TLS-derived displacement fields mentioned.
• Studying the softening mechanism of mudstone interfaces based on the described water-film formation and argillation.

Strengths

• Includes specific quantitative results, such as unconfined compressive strength decreasing from 4.90 MPa to 0.82 MPa.
• Describes a multi-sensor validation approach using TLS and pressure sensors, capturing deformation with a 140-minute lead time.
• Data is openly licensed under CC-BY-4.0.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small at 5.5 KB, indicating limited scope.
