Abstract

Provides guidance on the use of the Standard Penetration Test (SPT) in geotechnical engineering. Used world-wide in a variety of ground conditions, this simple test is relied upon to provide information about the properties of soils and weak rocks and as a basis for design. The report examines the variability of SPT results, whether caused by the methods of drilling and testing or influenced by ground conditions. The principal uses of the SPT are examined, i.e. ground investigation profiling, soil classification, the determination of geotechnical design parameters and for direct design. Suggested methods are proposed and outlined for the determination from SPT results of geotechnical parameters for granular soils, cohesive soils, weak rocks and chalk. Similarly, suggested direct design methods are discussed for the settlements of shallow foundations on granular soil, for piles in soils, weak rocks and chalk, and for estimating liquefaction potential and sheet-pile driveability in granular soils.
