The Study Of PCC Pile Force Mechanism And Working Performance Of Under Pile—soil Interaction

Pile foundation has high bearing capacity, good stability, small deformation of foundation settlement and difference, good seismic performance and has the advantages of the applicability of various geological conditions, are widely used in high-rise buildings, offshore drilling, large bridge construction, coast dock and large dynamic machine foundation in practical engineering. With the development of civil engineering and construction industry, the height of the building structure is higher and higher, and due to the growing uncertainty and structure of the address terms, domain environment increasingly close relationship, study of pile foundation under horizontal load and vertical load under the action of the internal force, deformation and failure mechanism can better solve practical engineering problems. Research work and the main conclusions are as follows:â‘ Under the vertical load and horizontal load under the action of combined action of pile and soil method, puts forward the applicable scope of the various methods and the advantages and disadvantages, so in the process of numerical calculation, need to select corresponds to the engineering calculation method, in order to improve the accuracy of the calculation results.â‘¡To establish a practical model of large diameter pile, the finite element modeling is discussed when the selection of unit selection principle and the unit should be paid attention to; Contrast analysis of the 3 d and 2 d finite element model of pipe pile under vertical load of pile stress calculation results, it is concluded that using 2 d finite element model can substitute for 3 d model of pipe pile- soil stress under the action of traits were analyzed, and the result can meet the requirements.â‘¢Research on different pipe pile under vertical load parameters on the behavior of pile stress and work performance influence, concluded that the influence of different structural parameters on the behavior of the stress of the pipe pile, for the selection of reasonable parameters of pipe pile in order to improve the safety of the pile and provides the basis for the working performance of the play.â‘£Discusses the traits and job performance effects of different pile parameters under horizontal load stress of pile, the pile bending moment and that affect the horizontal displacement of piles of different structure parameters under horizontal load and vertical load, the horizontal load bearing capacity of the pile body effects, and puts forward the structural measures pile stress failure to improve safety, pile under horizontal load.
