- W2365791838 abstract "In order to analyze the mechanical properties of frozen soil wall in deep thick alluvium,based on the Druker-Prager strength criterion,a frozen soil wall was treated as a thick cylinder made by functionally graded material( FGM) with the mechanical properties change parabolically with the radius. The analytical expression of stress in the elastic zone and plastic zone of the FGM frozen soil wall and the relationship between the external load on the frozen soil wall p and the relative radius of the plastic zone ρ were deduced. The results show that the radial stress increases with the increase of the relative radius r,and the hoop stress changes parabolically with the relative radius r. The plastic zone hoop stress of the frozen soil wall has nothing to do with the external loading and is related to the location. The calculation of a project shows that the external load p of the frozen soil wall at530 m equals to 6. 36 MPa. The load p approximately equals to the elastic limit strength 6. 33 MPa of the wall and is much less than the plastic ultimate bearing capacity of the wall,18. 89 MPa,which indicates that the frozen soil wall is safe." @default.
