| Abstract: | Tree linear transfer softening model and tree linear wholly plastic load transfer model are used separately for pile side soil and pile end soil.Based on soil mechanics and elastic theory,a set of analytical equations for the axial load settlement curve of pile top in layered ground are established.Meanwhile,based on soil mechanics parameter obtained by pile side friction force and deep hole testing at Zhuzhou area,the results acquired by this method are contrast to the testing results.Calculating results is conformable to the test results.Thereby the proposed method will be of practical significance in design of pile foundation. |
