Compare the axial bearing capacity piles cylindrical, tapered and semi-tapered in the sand by finite element method

Use piles with variable section can improve the bearing capacity of the piles, due to the larger cross-section upper part of piles. The function and easy implementation of semi-tapered piles that only the top half is in the form of a cone are better than the previous one. The purpose of this paper i...
