| Abstract: | By investigating the inner and the outer soil pressure on the cylinder wall and the base stress of the cylinder base,which were obtained from the model experiments,the interactions among the filler inside the cylinder,subsoil and cylinder are analyzed.The adjusting mechanism of the frictional resistance between the filler and cylinder wall,and between the subsoil and cylinder wall is discussed.Base on the experimental study,a method for calculating the base stress of the opened bottom cylinder structure is proposed. |

| Keywords: | opened bottom cylinder base stress frictional resistance additional moment |
