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
在此基礎上論文詳細歸納了以相對沉降為依據確定單位面積端承力q _ b的計算方法，並考慮擴底樁的「拱效應」特點引入了有效樁長的概念，最後結合公路規范推出了比較實用的人工挖孔擴底樁軸向承載力計算公式。論文運用了marc程序對地基土的應力和位移進行了有限元數值計算分析，得到了地基土的應力和位移場的變化曲線和在加載過程中樁側土摩阻力和樁端反力各自所承擔的比例；本文還在總結各國挖孔擴底樁應用情況的基礎上就擴底樁的構造進行了詳細的歸納。 -
