Technology Study On Construction Monitoring Of Arch Bridge With Two Independent Inclined Steel Box Ribs

More long-span bridges have been built with the rapid development of the humansociety, civil engineering techniques and communication, more attention has been drawn tothe safety, durability and normal functions of these bridges. the rigorous control ofcon-struction is the guarantee of achieving design objective of the cfst arch bridge, healthmonitoring systems and intelligent control technologies have been introduced into these longspan bridge and are developing rapidly, the key problem of construction controlling of archbridge with two independent inclined steel box ribs is studied in this paper.With the background of engineering practice of1stRiver Bridge of the Chan BaEcological Zone in Xi’an.First of all, introduce the method of construction control forextravertsive bridge, and it is analyzed briefly that which kind of construction methods will beused in different types. And than,detail extraversion general structure of arch bridge with twoindependent inclined steel box ribs,the finite element software ansys is used to analyzetheoretical calcutation.At last to control he construction process on the main line, the arch ribdeformation an stress of dual-control,and mainly to deformation and migration of the archaxis, taking into account considering th development of stress. Through the construction ofthe bridge as a whole process of comparison between simulation an actual moni-toring data, error analysis of construction control, so as to futher adjust the parameters forconstruction control to improve the quality of engineering.
