The Great Span Steel Braced Girder Bridge Peak Push The Construction Safe Monitoring And The Analysis

It is the essential step which the connection design and construct that the great spansteel braced girder bridge peak push the construction safe monitoring and the analysis, it isthe key link of the bridge construction and the construction, is playing the very importantrole to the bridge construction security, It will certainly to bring the very greatly economicefficiency and the project value to enhance the great span steel braced girder bridge peak topush the construction safe monitoring and the analysis technical levelThe object of this article studies is push the construction safe monitoring and theanalysis for the great span steel braced girder bridge peak, this article main research contentincludes1. Steel braced girder bridge survey method researchThe survey technical division is three stages: Namely traditional survey technology,electronic survey technology, intelligent survey technology. And we has carried on thesummary to these three kinds of survey technology good and bad points, finally proposesthe superiority supplementary principle.2. Went against to the steel braced girder push has carried on the outlineHas carried on the detailed division in the outline process to the bridge axle wire, threeimportant definitions is proposed, namely design axle wire, permanent pillar axle wire,bridge floor axle wire. It has provided conveniently for later narration bridge axle wire.3. Tacking some steel braced girder bridge of Hefei south as the project examplecarries on the construction safe monitoring and the analysis researchAs the theory and an engineering research project example, the link some steel bracedgirder bridge of Hefei south important operating mode axle wire displacement and theamount of deflection has conducted the research, We has obtained the magnanimous data tothe axle wire to carry on the analysis and the summary, it has provided the very valuabledata and the conclusion for later steel braced girder bridge monitor. We has carried on thetheoretical calculation ahead of time to the amount of deflection using the finite elementmethod, has carried on the confirmation with the actual value. The fact proved the finiteelement the method calculates the theoretical value and the actual value tallied basically, ithave confirmed the finite element method reliability.
