Abstract
Main pile with inlaid sheet structure is a kind of sheet⁃pile structure, whose calculation theory and design method remains unclear. Combined with a project case, a simplified calculation method was put forward in the paper, and relationship among main pile embedded depth, inlaid sheet embedded depth as well as width ratio between pile and sheet was formulated. Meanwhile, conventional m method and m method considering anchored point displacement were both utilized to calculate internal force of main pile, whose results were compared with those of finite element method. Based on ABAQUS, a 3D pile⁃soil model was built to study mechanical properties of the structure under different working conditions, and analysis was made about impacts of main pile embedded depth and rigidity on internal force of inlaid sheet. It is revealed that the anchored point displacement shouldn′t be ig⁃nored, and main pile embedded depth will reduce when inlaid sheet gets narrower and deeper. Main pile embedded depth has influence on the overall stability of structure, and internal force of inlaid sheet tends to be stable with the increase of main pile depth. Besides, increasing main pile rigidity helps reduce the stress of inlaid sheet. In order to save material, inlaid sheet could be made thinner appropriately.关键词
