Hi,
My company has asked me to check whether the addition of a "pile cap footing" at the top of a laterally loaded bored pile (say 1500mm diameter) will help reduce the embedment length of the pile, due to poor soil conditions/water table/unstable excavation at design depth. The pile design depth is 9m deep. Previously, they have received advice, to add a 2400x2400x1000 deep cap to the top to reduce the depth for overturning.
My question is regarding the analysis of the "pile cap footing" working in tandem with the bored pile to reduce the pile depth? How should I be approaching this in design?
Thanks.
