- 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
本文通过大量试桩资料和有限元计算分析，给出了以强度理论和相对变形为控制标准的人工挖孔扩底桩竖向承载力计算公式。其中特别论述了扩底桩地基变形模量的确定方法，并从mindlin解出发利用数学方法得出了影响地基土变形模量大小的因素?泊松比，初步确定了比较完善的变形模量计算公式。 - On this foundation the article inducts in detail the method which is based on the relative settlement of calculating unit area end support ( qb ) force at the same time considering the feature of pedestal pile ' s " arch effect " the article introduces conception of pile effective length and finally obtain t he formula of calculating man - made pipe with bulb - shaped axial carrying capacity . the article uses marc program to calculate and analyze foundation soil ' s stress and displacement and gets the change curve chart and the proportion that is shared by king - pipe side soil friction resistance and pipe end counterforce respectively . the article inducts the structure of pedestal in detail on the basis of generalizing pedestal application cases of many countries
在此基础上论文详细归纳了以相对沉降为依据确定单位面积端承力q _ b的计算方法，并考虑扩底桩的“拱效应”特点引入了有效桩长的概念，最后结合公路规范推出了比较实用的人工挖孔扩底桩轴向承载力计算公式。论文运用了marc程序对地基土的应力和位移进行了有限元数值计算分析，得到了地基土的应力和位移场的变化曲线和在加载过程中桩侧土摩阻力和桩端反力各自所承担的比例；本文还在总结各国挖孔扩底桩应用情况的基础上就扩底桩的构造进行了详细的归纳。
