Re: Pile Socket
(OP)
Hi all,
I have a few simple questions on piles sockets, have searched the internet but nothing seems to answer my question.
1.What is the purpose of socketing a pile into rock/clay/sand?
2.What dicates the length of socket?
Thanks all.

RE: Re: Pile Socket
Uplift capacity in rock is based on friction between the vertical surface of the pile and the rock.
The lateral resistance of the socket is based on passive pressure, same as for soil but the friction angle is higher.

RE: Re: Pile Socket
You asked about socketing into rock/clay/sand. The term socket is usually reserved for rock sockets, and refers only to the bottom length which penetrates rock rather than other soil. The length of the socket can be used to resist both gravity and uplift loads by skin friction.
RE: Re: Pile Socket
Knowing the compressive strength of the rock and concrete-bedrock bond stress, a socket depth is dictated for skin friction and end bearing.
I was involved in the field inspection for rock sockets. The socket inspection was done via camera. Pretty cool stuff!
