Basic Soil Mechanics

by Roy Whitlow is widely regarded as a cornerstone textbook for students and practitioners in civil engineering and building. First published in 1983 and now in its fourth edition, the book bridges the gap between theoretical soil physics and practical geotechnical design. It provides a comprehensive yet accessible introduction to how soil behaves as an engineering material, making it an essential resource for BTEC HNC/D and undergraduate degree courses. Core Principles of Soil Mechanics

1. Calculate the ultimate settlement (S = mv × Δσ × H).
2. Calculate the time for 90% consolidation (t90 = Tv × H² / Cv).
3. Install vertical band drains (reduces H, cuts time from 20 years to 6 months).

• where q is the flow rate, k is the permeability, A is the cross-sectional area, and dh/dl is the hydraulic gradient.

• Sieve analysis (Coarse-grained soils).
• Sedimentation/Hydrometer analysis (Fine-grained soils).
• Particle Size Distribution Curves (Grading curves): $D_10$, $D_30$, $D_60$.
• Coefficients of Uniformity ($C_u$) and Curvature ($C_z$).
