Then the pile-soil stress characteristics and stabilizing mechanism of the composite foundation are fully discussed. Based on the close analysis of the influence factors of the vertical bearing capacity, circular aperture extension theory is employed to establish the computing formulas for the pile vertical stress and the foundation vertical bearing capacity, respectively. Moreover, with analyzing the features of the calculation parameters such as materials of gunite mortar, jet pressure, diameter of the jet pipe, pile length, pile layout, a design theory for chemical churning pile composite foundation is proposed. Then, the variation of the pipe deformation with loads, the deformation coordination of pile and soil are studied. And methods to decide pile-soil stress ratio and the compressive modulus are developed. Meanwhile, the corresponding design method and the design parameters are proposed. In addition, studies for construction technique and quality detection of the chemical churning pile composite foundation are presented.
