This document provides a detailed explanation of the Standard Penetration Test (SPT), a widely used in-situ test to assess soil properties and geotechnical engineering parameters. The SPT involves driving a split-barrel sampler into the ground using a hammer, and the N-value (blow count) is recorded to estimate soil strength and density.
Additionally, the guide covers methods for calculating the bearing capacity of shallow foundations using SPT N-values, including empirical correlations and established theories (e.g., Terzaghi, Meyerhof, and Peck & Hanson). Engineers and geotechnical professionals can use this resource to interpret SPT results and design safe, cost-effective foundations based on soil resistance.
Key Topics:
SPT Procedure & Equipment
Corrections to N-value (Hammer Energy, Overburden, Dilatancy)
Correlations Between N-value and Soil Properties
Bearing Capacity Equations Using SPT N-values
Practical Examples & Case Studies
