Sorry, your blog cannot share posts by email. Despite its many flaws, it is usual practice to correlate SPT results with soil properties relevant for geotechnical engineering design. It is a simple and inexpensive test to estimate the relative density of soils and approximate shear strength parameters. The great merit of the test, and the main reason for its widespread use is that it is simple and inexpensive. How to Calculate Bearing Capacity of Soil From Standard Penetration Test? Manual on Estimating Soil Properties for Foundation Design.
ASTM C / CM - 18 Standard Test Method for Penetration Resistance of Hardened Concrete
For testing of computer systems, see Penetration test. Many local and widely published international correlations which relate blow count, or N -value, to the engineering properties of soils are available for geotechnical engineering purposes. Copyright - Geotechdata. As such, it is not totally applicable to agencies performing this practice. The SPT is used to provide results for empirical determination of a sand layer's susceptibility to soil liquefaction , based on research performed by Harry Seed, T.
