Results of field and laboratory research on cellular sheetpile structures are summarized. Design for both internal stability and overall stability is considered. It is proposed that for cellular bulkheads embedded in sands, neither sliding nor overturning can occur before a cell fails by tilting in the vertical shear mode. Guides for interlock force analysis and selection of lateral earth pressure coefficients for a newly proposed vertical shear model are given.
