Aquitard Model Parameters for Land Subsidence Simulation in Langfang City

9.5 KB of model parameters for aquitards used in a coupled fluid-solid numerical simulation of land subsidence. The dataset, authored by Yongjie Xie and last updated in May 2026, supports a study validating the Cam-clay model for aquitard deformation in Langfang City, China, using groundwater level and layered settlement gauge data from Danfeng Park.

Use Cases

• Calibrating Cam-clay model parameters for aquitards based on groundwater level and settlement monitoring data.
• Simulating plastic deformation (strain hardening, softening, critical state) in aquitards within pumping-affected zones.
• Comparing the impact of deep versus shallow groundwater extraction on pore pressure and land subsidence.
• Evaluating different groundwater extraction scenarios to inform resource development and subsidence control strategies.

Strengths

• Parameters are validated against monitoring data from a specific field site (Danfeng Park, Langfang City).
• Model is based on the Cam-clay model, which can capture yield characteristics under hydrostatic pressure.
• Dataset is openly shared under a CC-BY-4.0 license.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The 9.5 KB file size indicates a very limited parameter set, not a large observational dataset.
