The arch bridge is an ancient bridge type , has a glorious history in the history of China 's bridge . CFST arch bridge is applied on the basis of the ancient arch bridge concreting new technology in the steel pipe developed a new type of arch bridge , along with contemporary large - span bridges built , and more and more attention on bridge aesthetics , various span CFST tied arch bridge , especially some of the complex structure of the profiled arch bridge arch bridge built are required throughout the construction process of monitoring and control to ensure the safety of the construction , smooth . CFST Arch Bridge construction technology With the development of the times , has also been considerable development, several construction methods commonly used features of a brief introduction , content , method , and its importance , and construction monitoring related elaboration. Huzhou, Zhejiang Anji after the river arch bridge construction monitoring and engineering background , with a large-scale general-purpose finite element software ANSYS finite element model of the bridge construction stage analysis calculation . Arch bridge suspender Tied force tension adjustment as the main line of this article , a rigid support beam method , the rigid boom law , once off the the frames method three methods from different angles, a comparative analysis of the optimal adjustment of the tensile force , according to the results and Angelina after Creek arch Bridge 's actual situation , this paper, once off the shelf method can meet the design and construction requirements ; then once off the frame of the order carried the discussion and come to a from both ends to the middle of the frame drop sequence ; Finally Angelina after River arch Bridge hanging rod tension compared in order to calculate whether both ends to the middle of the tension sequence or in the middle to both ends of the symmetrical tension sequence were obtained satisfactory results . Finally , the time off the frame method to calculate the results of a comparative analysis of the measured data of the on-site monitoring , can be seen from the comparison of the results of the monitor to achieve the desired effect . A frame drop method used for the same type of bridge construction control a draw .
