Why we Conduct the SPT Test in Soil investigation?

As a civil engineer to check the geotechnical properties of soil, three guests must be performed the shear test, bearing test, and penetration test.

A penetration test is performed by three methods,

1. standard penetration test
2. A dynamic cone penetration test
3. Cone penetration test or Dutch cone penetration test.

In Geotechnical engineering, the value of standard penetration test is widely used for determining technical properties of soil.

1. To check the soil parameters
2. Value of cohesion and angle of internal friction with imperial relations.
3. To know the deformation modulus.
4. To check the consistency of soil
5. For determining the bearing capacity of soil

This test is globally used to determine various engineering and geotechnical properties for soil investigations.
