Why it matters
This tool walkthrough turns the N60 correction chain into a browser-side demonstration so a reader can inspect how each factor moves the final corrected blow count.
Workflow
- Start from the field-recorded SPT blow count.
- Confirm the hammer, borehole, rod length, and sampler factors.
- Apply the correction chain and inspect the resulting N60 value.
Output expectations
- A corrected N60 value in the standard reporting interval.
- A factor-by-factor trace the reviewer can inspect.
- A browser-run example that mirrors the recorded output bundle contract.
Limitations
This seeded walkthrough is illustrative and does not replace a project-specific factor selection or a full liquefaction interpretation workflow.
