Abstract: Based on the cylindrical cavity expansion theory considering the structural disturbance of soil and initial stress, the squeezing effect of bag pile is analyzed. The surrounding soil mass is divided into the elastic region and plastic region during the pile expanding. Considering the reduction of the in-situ soil strength caused by construction disturbance, a logarithmic in-situ strength disturbance function was proposed, and the soil sensitivity is introduced to describe the disturbance. Based ... More
