Aquifer Model Parameters for Land Subsidence Simulation in Langfang City

Model parameters for a coupled fluid-solid three-dimensional numerical simulation of land subsidence in Langfang City. The dataset, shared by Yongjie Xie on figshare under a CC-BY-4.0 license, was last updated in May 2026. It is a 5.5 KB Excel file containing parameters used to validate a Cam-clay model for aquitards against groundwater level and layered settlement gauge data.

Use Cases

• Calibrating numerical groundwater models based on aquifer and aquitard parameters
• Analyzing plastic deformation behavior in aquitards based on the Cam-clay model parameters
• Comparing the impact of deep versus shallow groundwater extraction on land subsidence based on scenario data
• Validating finite element models for land subsidence using pore water pressure and deformation data

Strengths

• Parameters are validated against groundwater level and layered settlement gauge monitoring data from Danfeng Park
• Includes data from 15 different groundwater extraction scenarios for comparative analysis
• Model employs the Cam-clay model, which can capture yield characteristics under hydrostatic pressure

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• Description metadata is limited; actual data quality requires manual inspection after download
