Interface stress distribution law of SMW method section steel-cemented soil

Based on equal cross area simplification of SMW method single pile section, SMW method section steel-cemented soil interface stress analysis model was built. By analyzing theory of cemented soil pile-section steel interface shear stress, distribution law of interface shear stress was deduced. Change rules of different axial load and cemented soil elastic parameters on interface shear stress were also analyzed contrastively. The larger axial load got, the greater peak value of surface shear stress was; The greater cemented soil modulus got, the smaller distribution range of surface shear stress was and the closer to ground surface peak position of surface shear stress got.
