LPile - Pile extending out of ground LPile - Pile extending out of ground mas745 (Civil/Environmental) (OP) 22 Jan 18 19:12 I have a pile design that is to extend 5 feet out of the ground and I was wondering how one would model this in LPile? RE: LPile - Pile extending out of ground GeoPaveTraffic (Geotechnical) 22 Jan 18 19:54 You would input the first soil layer starting at +5 feet instead of 0 feet.

That would be one way but i am sure that there is a way to model the pile extending above ground level other than the above. I am sure if you sent a sketch to the help team they would tell you.

In the design of the pile itself, don't forget to take into account the unbraced length of the pile, which will be min. 5 ft. + ineffective depth of top layer of soil (loose layer).
