Design Method Of Steel Deck Pavement For Long-span Bridges

With the vigorous development of our construction, orthotropic plate of steel box girder of the application to become the mainstream of long span steel bridge deck pavement technology in bridge construction has become one of the most important technology, but the bridge shop Loaded design still no uniform standard. View of the steel box girder bridge deck design, this paper analyzed by finite element method the force bridge deck condition, from the bridge deck structural design and materials, two aspects of the design of bridge deck pavement System, the decisive factor in the situation by force, combined with material testing system proposed pavement design index, commonly used indicators of the parameters of the design process and the scope of the proposed design.First, the use of finite element software to simulate the bridge deck, steel box girder bridge deck analysis of the mechanical impact, and determine their own critical load position, identify the most unfavorable load position. by Steel box girder structure parameters, load and other forms of stress on the pavement system, the impact of the situation, determine the maximum transverse pavement surface tensile stress is surfacing for damage control targets, the maximum longitudinal tensile stress is a secondary control indicators.Secondly, by calculating the established structure of the bridge deck pavement of the force, given the design parameters of the recommended range of bridge structures and from bridge deck structural design aspects, considering the climate, traffic volume and the common bridge Damaged pavement surface type, the design of proposed structural indicators.Finally, lateral loads on the bridge deck of the calculations to determine the bonding layer of waterproof material parameters on the impact of trends in bridge deck, and as a basis layer of waterproof adhesive material presented selected programs through Test validation; from the surfacing material design aspects, the design of proposed indicators of waterproof adhesive material.
