Study On Pile-Soil-Pile Interaction Effects Of Batter Pile In Deep Soft Soil

In spite of batter piles are widely used in bridge pile foundations and piled wharfs for subjected to horizontal loading, but there are no enough evaluation of pli-soil-pile interaction effects in design ,moreover, many batter piles are produced in construction and useing due to various causes . But at present, the research report about batter pile is rare, so correct evaluation of pli-soil-pile interaction effects to ensure the safety is great significance.Based on Bridge Pile Foundation Design In Deep Soft Soil Model Test and wide collection of relevant literature, using the finite element calculation results compared with the results of model text, batter pile of distribution of distribution of soil-structure interaction in deep soft soil. In this thesis, the main research results obtained as follows:The p-y curve of batter pile can be used hyperbola. Based on the summary of the model test and analyzing the sloping piles p-y curve ofthe value of the parameter, by useing the correlation of vertical pile and batter pile of axial force straight, load transfer method can be applied in batter pile soi-pile-soill interaction effect analysis.The top of batter pile occurred due horizontal displacement, make a certain range of pile body section bending, which producing the P -â–³effect. The bending moment of the same section increased with the degree of batter plie increased. Concrete could be broken as the large bending moment.Because of the inflection of pile deformation, the turning point of pile lateral friction on both sides appeared, the changing rule of side friction with batter degree is coordinated with the rules of inflection deformation and separation of piles and soil at the top of pile..
