A mathematical model is developed for the analysis of circular
cell bulkheads subjected to gravity loads of cell fill, backfill, lateral
pressure, and surcharge load using the finite element method. The
finite element circular cell model consists of axisymmetric triangular
and/or quadrilateral ring elements for soil and cylindrical shell elements...
