Civil Engineering - RCC Structures Design - Discussion

The answer should be all of the above.

Option A is end bearing pile.

Option C is friction pile.

Option B & C are the characteristic of pile.

The answer should be A as the pile is used where we don't get hard strata just beneath the GL to bear the building load. So this pile is used to transfer the load to the deep hard rock strata to transfer the load of the structure.

I think all the answers are correct. Because there are different types of piles like bearing and friction piles.

Question is incorrect as Pile transfer the load by End Bearing and Friction both,

In case of sand Load transfer is done by skin Friction generated due to friction between the pile surface and the soil particles around the surface of the pile.

In case of availability of Hard Strata at certain depth (mostly in case of BLack cotton Soil) Load transfer takes by point transfer of load at the end of the pile.

Also in many cases load transfer can be done by both Friction and End bearing for example in Coastal areas where sand is present over certain depth and then hard strata is available.

I feel all the options are correct.

The all above statements are correct.

I think all options are correct.

Actually answers is all the above. Any other piles are following the statement?

What about option D? Thanks in advance.

Yes, All the given options are correct.
