英文摘要	In collapsible loess area, the negative friction of pile foundation will cause many engineering problems, such as additional settlement of pile, failure of pile strength, and reduction of bearing capacity of pile foundation, which will do great harm to engineering construction. Therefore, it is very urgent to study the negative skin friction characteristics of pile foundation in collapsible loess area. In this paper, combined with the collapsibility of loess, the load transfer model of pile in single homogeneous loess foundation under t he action of pile top load and immersion load is established by using the load transfer method. The model comprehensively considers the pile-soil interaction and loess collapsibility characteristics, and can better reflect the nonlinear law of pile-soil load transfer. Combined with the actual engineering case, the theoretical calculation results are verified by the finite element numerical simulation, and the results are in good agreement, which shows that the proposed load transfer model of pile in single homogeneous loess foundation is feasible. The research results of this paper can enrich the theory of negative skin friction of pile foundation in collapsible loess area, provide a theoretical basis for further study of load transfer law of pile foundation in large thickness collapsible loess area, and have a certain reference value for pile foundation design in collapsible loess area.
