  1. Through a lot of test pile material, this essay concludes the vertical bearing capacity calculation formula of man - made pile with bulb shaped base by strength theory and relative deformation as control criterion. the method of defining pedestal pile foundation deformation modulus is especially discussed in this article, and it takes the mindlin solution as the starting point using mathematics method to get the poisson ' s ratio ( u ) which is the factor influencing foundation soil deformation modulus, and a deformation modulus calculating equation is finally determined

    本文通過大量試樁資料和有限元計算分析，給出了以強度理論和相對變形為控制標準的人工挖孔擴底樁豎向承載力計算公式。其中特別論述了擴底樁地基變形模量的確定方法，並從mindlin解出發利用數學方法得出了影響地基土變形模量大小的因素?泊松比，初步確定了比較完善的變形模量計算公式。
  2. Prediction of vertical ultimate bearing capacity of pile with bulb shaped base by using artificial neural networks
