Abstract

The Influence of the residual stress on the entire quality of U-sheet pile is introduced. The sectioning method and full release method are used to detect the surface residual stresses on quarter and half length place of the U-sheet pile. The testing principle of stress free method, experimental equipment and testing process are introduced in detail. The stress distribution on U-sheet pile is obtained. X-ray diffraction (XRD) method is used to validate the residual stresses on the same positions. The difference between the two testing methods is compared. Result shows that the stress gradient on the bottom sternum is comparatively larger. On the left side plate, longitudinal compression stress and transverse tensile stress are detected at half length positions, and opposite results are found at quarter length positions. On the right side plate, the stress states are coincident. Transverse stress presents difference between sectioning and full release method, because of the unreleased stress on transverse direction of sectioning method.
