Macro Parameters for Limestone-Concrete Composite Models with Size Effect Analysis

Hang Liu's dataset from 2026 contains macro parameters for multi-scale limestone-concrete composite models. The data likely includes results from uniaxial compression tests analyzing strength, deformation, and failure features across different model sizes and joint dip angles. The study was conducted using synthetic rock mass technology based on the discrete element method implemented in PFC.

Use Cases

• Modeling the size effect on uniaxial compressive strength (UCS) based on model dimensions up to 600 mm x 1200 mm.
• Analyzing the impact of joint dip angle on compressive modulus based on angle ranges like 30°–35° and 75°–80°.
• Studying failure mode transitions from global to dispersed localized failure based on energy release and crack propagation data.
• Comparing the sensitivity of strength versus deformation characteristics to size variations based on calculated difference ratios.

Strengths

• Data is derived from a controlled study using synthetic rock mass technology and discrete element method modeling.
• Specific stabilization dimensions (600 mm x 1200 mm) and percentage changes (less than 10% decrease) are reported for key parameters.
• Explicit joint dip angle ranges (e.g., 75°–80°, 30°–35°) are analyzed for their impact on size effect.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small (5.5 KB), indicating limited scope, likely containing summary parameters rather than raw test data.
