Civil Engineering - RCC Structures Design - Discussion

All the above cases are possible because these all are the mode of load transferred by the pile.

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.

The all above statements are correct.

I feel all the options 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.

Answer should be all of the above because End bearing piles are transfer load at lower end in a hard stratum, Friction piles transfer load by skin friction.
