对单桩负摩阻力的产生原因、产生机理、减少负摩阻力的方法、建筑桩基规范中负摩阻力的确定方法、负摩阻力中性点位置的确定、以及对荷载传递基本微分方程的推导都进行了论述。 - In order to reveal load mechanism and failure mode of thick pile caps , by means of the test of 1 / 4 - scale models of thick pile caps with six piles and post - handling study of 3 - dimensional non - linear finite element adina , this paper points out the shortage , which is that the design of pile caps is carried out by flexural strength in chinese technical code for building pile foundations jgj94 - 94 and american reinforcement concrete building construction code aci318 - 02 , promulgates that the failure mode of thick pile caps is punching failure and load transfer mechanism is the strut - and - tie , which is that zones of concrete with primarily unidirectional compressive stresses are modeled by compress struts , while tension ties are used to model longitudinal reinforcement over pile
摘要为揭示厚承台的传力机理和破坏形式，通过对4个1 : 5比例的六桩厚承台的模型试验研究与三维非线性有限元adina的后处理研究，指出中国建筑桩基技术规范jgj94 - 94与美国钢筋砼房屋建筑规范aci318 - 02规范中，承台以弯曲强度进行配筋计算的设计方法之不足，揭示出厚承台的破坏模式是冲切破坏，传力机理是以带有主要单向压应力的砼区域作斜压杆，桩顶区域的纵筋作拉杆的空间桁架。 - Secondly , this paper made some theoretic researches on its engineering classfication and applicable scope for this technology ; then combining with project example , this paper carried out scheme design for this technology , and compared some different kinds of underpinning scheme and node and structure design , and put forward the method of " reinforcce steel bar through column " to build pile cap beam , " resistant bend and shear anchored reinforce steel bar " to strengthen column consolidation effect , and the method of " steel plate hoop " to build reinforcing bar connection of the foundation beam , etc . in the process of the consturction scheme research and implement , this paper synthetically elaborated the organizaton for project construction , put forward the construction technical measure of specific aim on the artificial pile , and pile cap beam , and underground adding layer and structure stabilization , and overall structure stabilization and so on . for this project , adopt reinforcing bar concrete to brace hole wall to ensure the safety of engineering in the artificial pile construction , use flexible connection catch to make the cage hoisting easier to simplify the construction process , use the method of earthwork statified symmetrical balance in the process of underground adding layer excavation
本文首先对于基础托换与结构加固技术的目的和意义、国内外发展状况进行了综合阐述；其次对该项技术工程分类及适应范围进行了理论上的分析研究；然后结合工程实例对该项技术进行了方案设计，对比几种不同的托换方案和节点及构造设计，提出了“通筋穿柱法”做承台梁， “抗弯抗剪锚筋法”强化柱加固效果， “钢板箍法”做地基梁钢筋连接点等多项技术；在施工方案的研究和实施过程中，对于工程施工组织进行综合阐述，并就人工挖孔桩、承台梁、地下加层及结构加固、整体结构稳定等专项施工方案提出有针对性的施工技术措施，人工挖孔桩施工采用钢筋砼护壁确保挖孔桩的安全成型，使用柔性连接钩进行钢筋笼吊装简化施工工序；承台梁施工采用梁主筋横穿柱身化学胶锚固等；地下加层综合施工技术采用土方分层对称平衡开挖，分段挖土做筏基结构自稳等；最后对于该工程实施后的效果分析，说明该项综合施工技术的可行性。
