Standerd penetration test
The standard penetration test (SPT) is an in-situ dynamic penetration test designed to provide information on the geotechnical engineering properties of soil. The test procedure is described in ISO , ASTM D and Australian Standards AS
HOW TO DO STANDARD PENETRATION TEST (SPT) OF SOIL ON SITE?
Description:The test is extremely useful for determining the relative density and the angle of shearing resistance of cohesionless soils. It can also be used to determine the unconfined compressive strength of cohesive soils. The standard penetration test is conducted in a bore hole using a standard split spoon sampler. When the bore hole has been drilled to the desired depth, the drilling tools are removed and the sampler is lowered to the bottom of the hole. The sampler is driven into the soil by a drop hammer of
