Enrol today in our site learn.apsed.in/ and get access to our study package comprising of video lectures, study material, practice questions and test series with doubt support for Civil Engineering competitive exams of GATE, ESE etc starting from Rs.1599!
APSEd is an educational platform by IIT Bombay graduates. For queries, you can contact us by mail at [e-mail] or alternatively contact us at [phone]
In this video I have talked about the different type of tests that are conducted in the triaxial apparatus i.e. Unconsolidated Undrained test, Consolidated Undrained test and Consolidated Drained test.
Hello everyone, hope you liked the video. This is an educational platform set up IIT Bombay Graduates with an aim to prepare you for competitive exams like GATE, ESE, etc., and to widen your knowledge in Civil Engineering.

[@363vijay]

Thank you sir ....in less time you covered most complicated topic of soil and almost all answers related to triaxial test 🙏🙏🙏

[@alokverma8894]

Thank you sir for explanation of UU, CU & CD Conditions. It helped me a lot.

[@APSEDUVERSE]

Glad to hear that. Stay subscribed and keep watching this space for more videos.

[@INCREDIBLEINDIABYDIVYA]

Pahli bar is tarah se sanjh aya h ,,thanku

[@rhirendraprasad2905]

you are really very very helpful for engineering students
thanks a lot and keep working

[@RAKHEERANINaik]

a great help.................very good explanation...............................keep good work on

[@mohit6566]

It's a great explanation.... Feeling froud with study under iit graduates.... I request you.. Pls provide us notes also related to video it's difficult to write during lectures....

[@riteshdas1811]

Sir I have a question.. that all the test are performed before construction or after construction..??

[@viveksavaliya9464]

Why in normally consolidated Cu is zero and some value in over consolidated in consolidated drained test?

[@NileshRoamingNITIAN]

Awwweesome ♥️♥️🔥🔥

[@pop4ti]

Thank you for your efforts and explanation. How to convert the axial strain and axial stresses (what I get from the triaxial test) to shear strain and shear stresses?

[@co-de-code]

mohr circle

[@rushikeshpawar9946]

Best explained

[@wahyuaryo7367]

so helpful, thank you..

[@alenmanoj7169]

thank you sir.

[@hariomchandra9048]

What is the value of cohesion of clay in CU test and why is it so ,how ?

[@PankajSharma-lh5yk]

Your stuff is great!
Plz upload video for stability of slopes

[@PankajSharma-lh5yk]

Thank you sir and what about lecture number 32 and 33

[@sanjeevgupta9584]

vry nicey explained lecture ....sir plzz give the notes also

[@DeepakJaiswal-dh9lp]

Sir please explain why the C value is zero for NC soil????

[@viveksavaliya9464]

Why UU test is used at time of construction means immediately?

[@baishya775]

UU test is used to identify whether Faliure will occur once the construction is completed. This test is used to see whether the soil will be able to sustain the structural load or not.
The Other tests are used to determine the long term sustainability of the soil.

[@vaibhavbisla8742]

Why do we not perform UD test?

[@gavaskarmuppavaram9145]

because consolidation will occur whenever the specimens are opened during the shearing stage, so during testing no pore pressure is developed and it will be similar situation like consolidated drained

[@atifkhan3300]

Hi @apsed if anyone from your faculty have done this experiment on HUMBOLDT manual pressure triaxial test machine(advance version) please reply it will be a great help.

[@deepsarkar3260]

Any one can help me with the solution???
a consolidated undrained triaxial test was conducted on a saturated clay. when the confining pressure was 200 kN/m2, the sample failed at a deviator stress of 500 kN/m2. The pore water pressure was 150 kN/m2. The failure
plane occured at an angle of 60° to the horizontal.
lf the same specimen were tested in a drained test with a confining pressure of 200 kN/m2 then
the deviator stress of soil specimen is kN/m2.

Some segments in the video are stamped not adjacent to each other

[@hemrajjat3041]

Thank you

[@aswarthakappala690]

thanks a lot ur explanation

[@APSEDUVERSE]

Thanks aswartha.

[@victimboy7765]

good explanation!

[@APSEDUVERSE]

Thanks! Have you checked our site learn.apseduverse.com/ ? Video lectures covering entire syllabus with study material, test series and most importantly, doubt support! Starting from Rs.1399/-

[@haopham2251]

great summary but your hand writing is hideous

[@viveksavaliya9464]

Why in UU test,time of test is less?

[@baishya775]

Because we don't have to wait for the drainge to occur.
The other tests are long because we have to wait for the expulsion of the excess pore water pressure.
The CD test takes longest because we have to wait for the drainge to occur in two stages.
First when the confining pressure is applied thats is also known as consolidation test.
Second is after the application of deviator stress or the excess normal stress.

[@atifkhan3300]

If anyone have done this experiment on HUMBOLDT manual pressure triaxial test machine please reply, it will be a great help.

[@IzaanSaiful228]

Hello, could you please explain how could you get the effective failure envelope for UU test?? It goes through only one point. and I cant understand.

[@co-de-code]

IT CAN'T BE DEFINED AS THERE IS ONLY ONE CIRCLE

[@viveksavaliya9464]

How in over consolidated soil pore pressure is negative?

[@chetangunti3965]

because volume tries ti=o increase

[@mayanksharma9007]

✌✌👌👌👌

[@vivaan1889]

Your writing skills 😅

[@seemaghogare3388]

Nice

[@RahulKumar-iq3fd]

Bhai thoda thik se bola and likha karo

[@APSEDUVERSE]

Hi Rahul, will sure try to improve. It is written with a digital pad, so it s quite difficult to replicate as we write in notebook.
