Abstract

As a new structure with sloping arch ribs and curved main beams,a skewed arch and curved beam bridge markedly differs from the conventional bridge in construction monitoring technology due to its complex structure and prominent spatial effect.To investigate the key technology in construction monitoring,this study took a long-span skewed arch and curved beam bridge as the engineering background and discussed construction process simulation analysis,field monitoring,and parameter identification and adjustment of the bridge.The results show that the plate-shell unit model has higher calculation accuracy and can comprehensively show the stresses in all directions of the bridge compared with the beam element model.Additionally,in response to the limitations of the traditional influence matrix method in cable force adjustment,an improved method based on sequential quadratic programming optimization was proposed,addressing the issue of inapplicability in cable force optimization.The research findings can provide theoretical references and technical support for the construction monitoring of similar bridges.
