Abstract

From the aspect of a pile foundation in a structural loess area, this study analyzes the relationship between the generalized shearing strain and the generalized shearing stress of the soil mass around the pile under single pile reaming on the basis of the theory of cavity expansion. Through a triaxial test, this study generates the generalized shearing stress and strain relations under different stress levels. Loess structural parameters are introduced into the analysis of single pile reaming, and the attenuation changing rule of the loess structural parameters resulting from the reaming effect is studied. Under the influence of single pile reaming and within approximately two times of the pile radius from the pile axle, the structural parameter attenuation of the loess is severe. The influence range of single pile reaming is approximately two times of the pile radius, and the range exceeding four times of the pile radius is basically not affected.
