| The negative friction resistance of the pile foundation was an earlier proposed concept used in architecture.The concept was proposed by two scholars,Terzaghi and Peck,and the time was 1948.With the extension of time,the concept is used in more and more concepts of actual architecture,and people’s understanding of this concept is getting deeper and deeper.Computer-related application technologies are also very popular.It is more and more convenient to use computer technology as an analysis of technical parameters.It is more and more common to use existing data analysis to study actual application data.With the birth of related requirements,the corresponding software used for data analysis also appeared and became more and more flexible.This also makes the related work more relaxed,and is willing to be accepted and one of the more representative software in it is ABAQUS.As a data analysis software with compliance,it is highly praised by many people in the same industry.The focus of this paper’s research is to summarize and analyze the previous research data and use related data analysis software to study the negative friction resistance of the building piles under normal conditions after settlement of the construction site.The impact,as well as the study of the characteristics related to the negative frictional resistance generated by the piles with broken piles,through the engineering case study of an economically affordable housing in a building in Yuxi City,Yunnan Province,has resulted in the following conclusions:(1)First introduced in detail the related concepts of negative friction resistance generated by the construction pile foundation,and the reasons for the formation of the negative friction force generated by the pile foundation and the serious harm of this friction force in the use of the pile foundation.The study of this issue mainly starts from four aspects.First,it introduces the current status of this situation,starts with the problem,analyzes the reasons,and finds solutions to the related problems.(2)According to the reasons,select the appropriate experimental object,for example,the subject of this paper’s research is a single pile.The single pile in this research object is affected by the ground loading,determines the research object,and then selects The corresponding software for the analysis of the data,this time selected the finite element data analysis software ABAQUS.For the data analysis,select the appropriate relationship between the pile body and the soil between the body structure,considering the structure of the pile-soil in the data selection.In the case of contact interfaces,a related research model was established,and through the analysis of the data,the data of the impact of negative friction of the pile foundation was obtained.(3)According to the data analysis,the corresponding finite element model in the two-dimensional environment combining the superstructure data of the building and the lower foundation of the building is established.These model selection studies mainly include beam or column axial forces as objects.Research.(4)At the same time,the experiment also established a finite element model of the three-dimensional structure of the building under the group pile foundation,studied under different circumstances,and obtained the data of the study,from which to analyze the impact of the. |
