The Standard Penetration Test (SPT) is a much-loved test and specified on the majority of UK ground investigations but do practitioners and clients truly understand its origins and limitations when used to determine parameters? During this webinar replay, AGS members will provide facts about the SPT test, its use or misuse, limitations and potential future developments.
This webinar provides the background to the SPT and its humble origins, and how its use has evolved over the decades to become the most used in-situ test in the UK. It aims to distinguish the facts from the myths and compare the results with other sampling and testing methods.
The panel debate why the SPT is so widely used yet current standards appear to discard the test. They also discuss how it is used in geotechnical design, suggest alternatives and debate whether this test fits into the 21st century which thrives on electronic and data capture to be used with analysis models of evolving complexity and power. Finally, the panel examine whether the rudimentary results have the reliability to be used in today’s evolving and complex analytical software.
