Multi-span Continuous Beam Landscape Bridges Operate On The Deformation Properties

With the social development and bridge technological progress, the demand for more diverse bridge function, to meet the basic requirements under normal traffic, and more emphasis on appearance of the bridge harmony with the surrounding environment. Thus, the construction of a large number of domestic and sleek at the same time to show the local landscape characteristics and cultural bridges, many bridges have become a symbol of local, become publicity show featuring local culture and art of a carrier. Compared to ordinary bridge, landscape bridges have a great two construction loads and loads of people moving, therefore, in view of the bridges operate more easily deformed situation is too large and must be studied on the deformation properties of the operator.Thesis of a multi-span continuous beam bridges landscape as the research background, access to a large number of domestic and international information, summed up the views of the development process and the characteristics of the bridges on the impact of multi-span continuous girder bridges landscape deformation properties of the factors and computing operations theory made a detailed presentation, using the finite element software to build bridges calculation model, were studied creep and shrinkage of concrete, environmental temperature humidity chang,eprestressed loss, and reduce the impact on the operating performance of the deformation bridges crowd moving loads, combined Gallery beam deformation measured operating data for three years, its safety in operation period analyzed, while a continuous girder bridges with ordinary landscape continuous girder bridge for comparison of different deformation on both affected, in addition Secondary Loads of bridges and relationships building materials chosen to do a preliminary analysis.The research results have been applied in a multi-span continuous girder bridges landscape monitoring operation period.
