Ablation Experiment Setup for GCPSO-GIT Ground Motion Inversion Model

Bo Sun's dataset from 2026 contains the experimental setup for a ground motion inversion model combining Generalized Chaotic Particle Swarm Optimization and Generalized Inversion Technique (GCPSO-GIT). The 9.5 KB XLS file likely details parameters and results from tests demonstrating the model's performance in decoupling source, path, and site effects. Results cited include a site effect variation coefficient peak of 12% and a median source stress drop of approximately 42 bar.

Use Cases

• Validating the GCPSO-GIT model's parameter decoupling performance based on the reported Coefficient of Variation (CV) metrics.
• Benchmarking source parameter estimates like stress drop against other inversion methods.
• Calibrating seismic design response spectra for site classes using the reported 5.3% correction error for Class C sites.
• Assessing ground motion simulation accuracy using the reported peak ground acceleration deviation (2.7 m/s² vs. 2.8 m/s²).

Strengths

• Model performance is quantified with specific metrics: a 12% peak site effect variation coefficient and a median source stress drop of ~42 bar.
• Application-level errors are provided, such as a 5.3% correction error for seismic design spectra and a 6.2%–8.1% deviation rate for major project parameters.
• The framework's computational efficiency and generalizability were evaluated via cross-verification with the KiK-net database.

Limitations

• Row count and specific column definitions are unknown, requiring inspection after download to understand the data structure.
• The dataset's 9.5 KB size suggests it contains configuration or summary results, not raw seismic waveform data.
• The description focuses on model methodology and results; the actual data file content and format details are sparse.
