  1. 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。
  2. This research is to eject some compressed air into the dredging pipe to get tri - phase flow in the pipeline, and research the change about the pipe resistance, at the same time, obtain the more effect adding gas method and realize reduction friction and prolong the dredging distance

    本文研究的目的是在一定的漿體流速和漿體濃度下向輸送管道中加入一定量的氣體，在管道中形成三相流，進而探討加氣后管道流動的變化規律，同時確定出比較有效的加氣方案，從而實現減少阻力延長排距的目的。
  3. 6th, wear resistant, pipe wall friction coefficient low, the resistance to flow is small, delivery capacity

    6耐磨性強，管壁摩擦系數低，流阻小，輸送能力強
  4. Depending on different natures of materials to be conveyed, the pipe inner surface can be lined with a metal either the same as or other than the pipe base metal by means of the plastic deformation complex technique so as to meet the following requirements : 1 ) increasing both corrosion resistance and wear resistance of the pipe inner surface ; 2 ) reducing the friction factor and the resistance against the materials being conveyed in the pipe line ; 3 ) easy processing, installation and maintenance of the pipe line

    根據輸送物料的性質，採用塑性變形復合方法在管道內壁鑲襯異種或同種金屬管，可以實現以下目的：增強管道內表面的耐腐蝕性和耐磨性；降低摩擦系數，減小物料的輸送阻力；便於管道的加工、安裝和維修。
