In this paper, a high performance sma system applied to steel bridge deck is put forth in allusion to the pavement project of the wuhan junshan yangtze river highway bridge. it comprises steel slab, zn coating layer, closing layer, adhesive, pre - mixed asphalt stone and dual layer sma from bottom to top. it is based on the fea results of the forces and deformation of the pavement layer by means of the algor feas, according to this bridge ' s traffic and the ambient temperature varying range of the pavement layer
本文針對武漢軍山長江公路大橋鋼箱梁橋面鋪裝工程，從鋪裝層環境溫度變化范圍、交通量等使用條件出發，在用algorfeas有限元分析軟體分析鋪裝層受力變形基礎上，提出了（即鋼板+金屬鋅塗層+封閉層+粘接劑+預拌瀝青碎石+雙層sma ）的高性能鋼橋面sma鋪裝體系，並對這種sma的組成材料，包括改性瀝青、集料、礦粉、纖維進行了比較研究，設計了這種sma的配合比，對sma混合料的性能進行了對比試驗，對這種sma方案進行了疲勞性能研究，驗證了所選擇sma方案的可行性。 -
The shenzhen rainbow bridge is near to the northern railway station, which has big cut bag to span over twenty - nine tracks. arch bridge structure, which has a widely application these years, is taken considering of the bridge height limitation and the site used in downtown. the girder of the bridge is constructed with composite structure of steel and folding concrete slab
深圳市彩虹大橋地處深圳火車北站，需跨越29股火車軌道，跨徑大，又處於市中心，對橋梁的梁高有所限制，經研究分析，採用近年來廣泛應用的鋼管混凝土拱橋橋型，梁體採用鋼- -混凝土疊合板組合梁組合結構。 -
Zhaihe bridge was taken as an engineering example, in - situ tests of deflections and stresses of the concrete slabs of 10 conditions before and after steel rods plantation and transverse pre - stresses execution, and the testing shou reveal that steel rods plantation can protect the assemble type concrete slab bridage deck, increase the bearing capacities of bridge and decrease the deflections, which provide basis for related engineering about reinforcement of bridge deck
以寨河橋為工程實例，進行了植筋和預應力張拉前後10個工況的混凝土板撓度和應力的現場測試，結果表明，植筋等增加橋面預應力的措施確實能夠預防橋面病害的發生，並能提高橋面的承載力，減小撓度，為相關工程提供了依據。 -
On the basis of relative researches in the world, according to the study status of steel - concrete composite slab, which would be widely used in modern bridge, modified equivalent inflexibility of steel - concrete composite slab was deduced by use of conversion section principle in this paper ; based in this, this paper put forwards the theory of ultimate flexural capacity of steel - concrete composite slab in consideration of slip effect, and introduces the practical simplified method for calculating flexural deformation of steel - concrete composite slab in consideration of the effect of steel studs and welded wire, and conclude that the methods in this paper is veracious and reliable, comparing with the traditional calculating mode ; morever, this paper put forwards the calculating theory and program of the effect analysis of creep and shrinkage to steel - concrete composite slab, using conversion elastic modulus principle, and testifies that the theory is right and the program is reliable and practical
本文在國內外研究成果的基礎上，針對壓型鋼板與混凝土組合板結構在現代橋梁建設中廣泛應用前景和研究現狀，利用換算截面法導出了壓型鋼板與混凝土組合板結構的修正等效慣性矩；在此基礎上，又推出了考慮壓型鋼板與混凝土之間的相對粘結滑移影響的壓型鋼板與混凝土組合板結構極限抗彎承載能力計算理論，並介紹了考慮栓釘、聯結件影響的壓型鋼板與混凝土組合板結構簡化實用撓曲變形計算公式，而且通過與傳統計算理論的分析比較，表明本文提出的計算理論公式的準確可靠性；此外，採用換算彈性模量比法著重提出了壓型鋼板與混凝土組合板結構的徐變、收縮效應分析的計算理論和程序，並通過實例分析計算證明了理論的正確性、程序的可靠性和實用性。 -
To plant steel rods in the assemble type concrete slab bridge deck and execute transverse pre - stresses not only can strengthen links between the assemble type concrete slabs and the bridge deck, but also can strengthen the transverse entirety of the whole bridge structures, and intensify the resistance of the bridge to active loads, vibrations and abrasions
摘要通過在裝配式混凝土板板頂植筋並對橋面施加橫向預應力，不但可以加強板與橋面鋪裝層的連接，而且還可以加強整體結構的橫向整體性，增強結構對動載沖擊、震動、磨耗抵抗能力。
