Standard Penetration Test (SPT)

For full course visit our website :
www.machenlink...
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

[@markombao3653]

Hi

[@umair20091]

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?

[@maulikbhimani8550]

Superb explanation plz upload more video

[@nkyadav1983]

Good Congratulations

[@deepaknaik9732]

I have a doubt if nc/nr is greater than 2 after dividing it by 2,what will be the case

[@chandrashekharmathur7365]

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.

[@yourfriend4314]

Can you pls post this same video in english

[@nitinsharma9663]

A channel named techno construction has copied your same video,I think so he has screen recorded it Just search STANDARD PENETRATION TEST and the video will be there with almost 350 view the thumbnail is different rest everything is same Thank you

[@MachenLink]

Thanks Kyzer we reported.

[@muhammadabdulmudassir4259]

Awesome sir

[@solinakeo5261]

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)?

[@nickdesignstudio4580]

Yes you are right

[@Anandpandey01]

Whereas I think u want to do phd in spt topic 🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣

[@swatibharti4695]

More videos sir please

[@hazycjaved3204]

Thank u so much sir

[@bharathrambabu]

Sir what about dilatancy correction, if the n value is greater than 15.

[@anshuldangi1612]

very helpful

[@EngineerHassan08]

Thanks Sir ☺️

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

[@MachenLink]

Language is mix of English and Hindi (Indian).
