According to the original assumption, this theory should be applied only to long, thin beams loaded in pure bending .
2.
Member shear beam load shear beam
3.
Beam loading impedance
4.
Finally , an example of circular jacking pipe constructed by smw method was analyzed , cws ' s specificity of material zoning in circular direction was clarified . the paper ' s main research findings are to propose ring - beam load - distribution theory provide cws ' s calculation method and program software
