Truss Type Cfst Arch Bridge Construction Monitoring Technology

The steel pipe concrete arched bridge has a beauty of bridge and crosses over the ability strong, start construction the period short etc. It is a favorable model for the long-span arch bridge structure. The construction control of the bridge is the assurance that the bridge constructs the quantity, measure a bridge of quantity standard be toes guarantee that the bridge is subjected to the deformation and the internal force state of each members of this bridge were within the specialized range of bridge design norms, the construction control can link up availably greatly design and constructions of across the path steel pipe concrete arched bridge, carry on the construction control towards acrossing the path steel pipe concrete arched bridge greatly, must.The beam-arch assembled Pushan great bridge is set a project example in the paper.carrymg on the beam-arch assembled steel pipe concrete arched bridge construction control technique research, the main work do and get the main conclusion of as follows:1. Carried on the design to recheck to check to calculate to Pushan great bridge, calculation result enunciation, both the deformation and the internal force state of each members of this bridge were within the specialized range of bridge design norms, so that the stress state of this bridge structure was rational.2. Carry on imitating the true calculation analysis to Pushan great bridge construction process, get the concrete filled and the arch rib support unload the internal force and deformation of bridge, making up reasonable of bridge construction project; Give the each main construction stage internal force and deformation of bridge, providing to prepare the arch degree and the suspender force reasonablely, computing the income result to guide bridge the construction has the important meaning.3. According to the characteristic and construction technique of the arch bridge, a detailed bridge construction scheme was made. By the practice of the bridge construction control, the deformation and internal forces of the bridge are under the design request. From the practice of the bridge construction control, the arch bridge has achieved the purpose of the construction control.The computation and actually measure result of this dissertation had applied to the practice of construction of Pushan great bridge, guide the construction of Pushan great bridge, insure the bridge construction safety combine realization design intention, and obtained preferable effect.
