Which of the following statement is/are correct.
1
The group efficiency of a pile group may be either less than 100% or more than 100%
2
Batter piles are driven at an angle with the vertical to resist a lateral force.
3
The negative skin friction is caused by the relative settlement of the pile and the skin frictional resistance is caused by the relative settlement of soil.
4
In the case of under-ream piles, most of the load is transferred through skin friction.
