Abstract


Composite pile foundation can take full advantage of the characteristics of settlement of the carrying capacity of the pile foundation and control , as well as to take full advantage of the pile cap foundation soil bearing capacity , thereby reducing the with piles amount , reduce the impact on the environment , security and economic purposes , these advantages it has been widely used in soft soil area . In this paper, based on the load transfer method , it is assumed that there is a relative displacement between the pile - soil pile - soil interaction is the relative displacement of the non-linear function to simulate the pile - soil between the the relative displacement and plasticity role of , this article termed \This method can also consider the soil around the pile of plastic and pile - pile interaction analysis of pile groups . This paper analyzes the settlement of composite pile foundation bearing characteristics , combined with existing and proved to be a viable theory , research and analysis to calculate the composite pile foundation settlement . The same time , from the point of view of the pile - soil - cap interaction , the system analyzes the overall working properties of the composite pile foundation . Engineering practice has a certain significance . In order to verify the paper analyzes the feasibility of the calculation method , practical engineering application of composite pile foundation settlement control , and comparative analysis is based on the calculation results and monitoring data , in general terms , especially in settlement calculations , the proposed method made very good results .
