Abstract: With bilinear load transfer function，a set of equations for the axial load-settlement curve is established; furthermore, it is applied to the load-settlement of pile. Then hyperbolic load-settlement curve is applied to soil; an analytical formula for analyzing pile-soil stress ratio under the interaction of pile and soil is deduced; and the influence of several relevant parameters on pile-soil stress ratio are discussed. The study shows that the pile-soil stress ratio of soil-cement pile composite foundation is not only related with the characteristic of surrounding soil of the pile, but also dimension, elastic modulus of the pile and the total load of composite foundation. It provides a new way for the calculation of pile-soil stress ratio of composite foundation.

Key words: soil-cement pile, composite foundation, pile-soil stress ratio, bilinear hardening model
