Lateral deflection of raked/batter piles
Lateral deflection of raked/batter piles
(OP)
Dear Sirs,
I am curious to know if there is a reliable way of modelling (by hand-preferably) the bending moment response of a batter pile due to induced deflections resulting from consoliation settlements in a layer of soft material(6-7m deep) below an embankment (6-7m high) which has been preconsolidated by compaction and other ground improvement methods (and therefore will not settle as much as the soft material). The embankment supports a high level seating beam for a bridge (as obviously do the piles). The piles are bearing on rock. Any insight into ths would be greatly appreciated!

RE: Lateral deflection of raked/batter piles
Assuming you have fixity in the pile below the soft layer (you'll have to decide just how far you go below the soft layer before true fixity occurs), then the pile becomes a cantiliver beam with two different, variable loads...the load of the compacted embankment and the load of the soft material (+ any material below the soft material but above the point of fixity).
