This standard provides a comprehensive glossary of definitions and standard symbols for terms commonly used in soil mechanics, foundation engineering, and geotechnical investigations. It ensures uniform vocabulary and notation in technical reporting and communication across India.
Glossary of terms and symbols relating to soil engineering
Quick Reference Values
Symbol for Void Ratioe
Symbol for Porosityn
Symbol for Water Contentw
Symbol for Liquid LimitwL
Symbol for Plasticity IndexIp
Symbol for Coefficient of ConsolidationCv
Symbol for Compression IndexCc
Key Formulas
e = Vv / Vs — Void ratio definition
n = (Vv / V) * 100 — Porosity definition
Sr = (Vw / Vv) * 100 — Degree of saturation
Ip = wL - wP — Plasticity Index
Practical Notes
Standardized symbols from Appendix A (like 'e' for void ratio, 'wL' for liquid limit) must be used in all geotechnical reports and logs to prevent misinterpretation.
Highly useful as a reference document for drafting technical specifications, contracts, and academic materials relating to earthworks.
