Soil Mechanics – Unified Soil Classification System (USCS) Gravel Soil Examples | GEOtExcel Spreadsheets

[GEO-2025-0112] – By Dr. Ahmad Fahmi

We are excited to introduce the Unified Soil Classification System (USCS) Gravel Soil Examples spreadsheet pack as part of the GEOtExcel (2025-1) collection. This 20-sheet bundle is designed for geotechnical engineers, soil mechanics students, and civil engineering professionals looking to classify gravel soils using the USCS system based on sieve analysis and Atterberg limits.

What’s Included in the 20 Spreadsheets?

  1. DATA: Unified Soil Classification System data series with sieve analysis and Atterberg limits.
  2. Data Form: Standardized data form for sieve analysis and Atterberg limits tests.
  3. Analysis Sheet-Empty: Empty sheet template for soil classification based on USCS data.
  4. USCS: USCS process table to help classify soil types based on test results.
  5. Examples: Example table with five examples of gravel soils classification using USCS.
  6. Example 1 – GW: Well-graded gravel classification.
  7. F1: Data form for sieve analysis and Atterberg limits for Example 1: GW.
  8. S1: Soil classification analysis sheet for Example 1: GW based on USCS.
  9. Problem 2 – GP: Well-graded gravel classification example.
  10. F2: Data form for sieve analysis and Atterberg limits for Example 2: GP.
  11. S2: Analysis for soil classification for Example 2: GP.
  12. Problem 3 – GC: Gravelly clay soil example.
  13. F3: Data form for sieve analysis and Atterberg limits for Example 3: GC.
  14. S3: Analysis for soil classification for Example 3: GC.
  15. Problem 4 – GW-GM: Well-graded gravel-silty gravel example.
  16. F4: Data form for sieve analysis and Atterberg limits for Example 4: GW-GM.
  17. S4: Analysis for soil classification for Example 4: GW-GM.
  18. Problem 5 – GP-GC: Well-graded gravel-clay gravel example.
  19. F5: Data form for sieve analysis and Atterberg limits for Example 5: GP-GC.
  20. S5: Analysis for soil classification for Example 5: GP-GC.
