Description:
This test (IS: 2131 - 1981) is performed in a clean hole, 100 to 150 mm in diameter.
A casing or drilling mud is used to support the sides of the hole.
This test is most commonly used for cohesionless soil which can not be easily sampled.
Useful for determining the relative density and the angle of shear resistance.
It can also be used to determine the unconfined compressive strength of cohesive soil.
The test shall be made,…
At every change in the stratum
At intervals not more than 1.5 m
If the number of blows for 150mm exceeds 50 it is taken as a refusal and the test is discontinuous

Hi
I have a doubt if nc/nr is greater than 2 after dividing it by 2,what will be the case
Superb explanation plz upload more video
Thanks Sir ☺️
Nice representation
best way explained
More videos sir please
Sir Bahut Gajab
nice presentation you have explained very well
Plz provide more videos of foundation design
You said that the cuttings come out from the annular space between casing and drill rod. But this space will also be filled up by soil inside the casing. Please clary this doubt.
If the no of blows greater than 50 ,"refusal occur" than it is ok or not.means soil is very dense .test is ok or not?
Sir what about dilatancy correction, if the n value is greater than 15.
Sound is very low.
Nice presentation Sir. ओम शांति
Can you pls post this same video in english
Thanku sir
Nice sir
Increase the volume please 😫🙏🙏💓😫🙏🙏💓
Super 👌 👍
Thanks
What is good spt value?
Other correction b btao sir.
Thank you so much for your video. Yet, can you make another video about 1. advantages and disadvantages of using SPT, and 2. compare it to geophysical methods (electrical resistivity survey)?

As useful as the video is it appears the speaker wasn't speaking English at a time. Or may be the huge accent is the difference
