| In recent years, as a general city overpass and viaduct built bridge, this bridge has been developed greatly as simple and smooth shape, building height is small, the visibility under the bridge, adapt to situations and more convenient for construction, and low cost advantages, due to the unique bridge-type force characteristics, the static analysis and study of Reinforcement is relatively lagging behind. To ensure that research on the whole-plate girder bridge of single column reinforced and strengthened, Based on the engineering background of QingTangBa Bridge in ChangXing County, Zhejiang Province, on the single column as a whole-plate girder bridge force characteristics and reinforcement principles was researched.The main research contents and achievements are as follows:1. Based on thin plate theory, finite element method for beam element model and solid element model analysis of the vertical and horizontal characteristics of a whole-plate girder on single column bridge, finite element method using space on the diaphragm beam, top of pier, side cross-side cross-beam and main beam across the critical junction node of the local mechanical properties, for the kind of reference for the design of bridge reinforcement.2. Type of bridge for the force characteristics of the finite element method results, select the appropriate reinforcement method, using large-scale finite element program of the bridge longitudinal and transverse reinforcement of research, summed up the kind strengthened by bonded steel bridge reinforcement theory.3. The specific circumstances of this bridge to carry out mention of containing the potential to develop a feasible reinforcement, described in detail strengthened by bonded steel construction technology, strengthened by bonded steel construction to provide a reference.4. After the load test through the reinforcement effect was assessed on the reinforcement, structural reinforcement to achieve the desired effect.
