摘要
Abstract
This paper aims to address the design defects and severe consumables of the existing ten-sioning pedestal with fold-line pre-tension method.Combined with the construction of prefabricated I-beam of the approach bridge of a super-large bridge in construction,the study presents an improved new tensioning pedestal-pile plate tensioning pedestal suitable for the prefabricated I-beam of the fold-line pre-tensioned method,which involves studying its tensioning end structure;performing a structural model of the tension end in the pile plate tension platform by finite element software Midas FEA NX;analyzing its stress and deformation in the process of precast tension;and designing a tension end of the pile plate ten-sion platform and a welding part of the uplift pile.The calculation results show that the proposed bearing capacity and deformation of each end at the tension end of the pile-plate tension pedestal can meet the re-quirements of field construction and standard design.关键词
