| Abstract: | Based on Winkler's hypothesis foundation model presumes,a variable cross-section pile is optimally designed by the way of finite element method and gradient method.The paper illustrates that the pile can save 45% concrete depending on an example,under meeting pile capacity condition.The optimal result needs to be proven feasible in practice.Valuable proposals are also presented in the paper. |
