Abstract:During the driving process of steel-pipe pile and concrete pipe pile,the squeezing effect and plugging effect will be generated. At present,the plugging effect is emphatically studied for steel pipe piles,and much attention is paid to the squeezing effect of concrete pipe pile. The state-of-art on squeezing effect and plugging effect of the pipe pile are firstly reviewed. Considering the plugging effect of the pipe pile,the cavity expansion theory is applied to studying the squeezing effect of pipe pile. Based on the reasonable assumptions,the elastoplastic analytical solutions for stress field and displacement field of the soil around the pile are presented. This new way can be employed to study the squeezing effect and the plugging effect synthetically.
