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。A great amount of post tensioned pre - stressing concrete single box beam for double track ( as called the box beam hereinafter ) has been used on the line. it is of infeasibility in adoption of the traditional practice of pre - fabrication in precast factory and erection of the box beam with the track laying machine for that this type of beam is characterized by new structure, complicated workmanship, large volume and difficulty in transportation. therefore, the key and hardest problem to tackle is that what processing should be adopted to precast the box beam on site and that what kind of machinery should be used to transport and erect the box beam
由於該型梁具有結構新、工藝復雜、體積大、運輸困難，將常規鐵路的橋梁廠製造橋梁、經過鐵路運梁到工地、邊鋪邊架進行橋梁製造與架設的傳統施工模式應用到該線是行不通的，必須在現場預制橋梁、並採用專門的運架梁設備進行橋梁架設，因此箱梁的製造、架設施工成為該線施工技術攻關的重點和難點。During the 3d finite element calculation, try to simulate different procedure of the construction ( like sunk well in - filling, main cable erection, box girder hoist, bridge flooring and opening to traffic ). and then, reveal the regulation of deformation and displacement on the foundation and soil during different period. after got these, this thesis put great attention on the analysis of the reason which cause the horizontal displacement of the cable saddle, as well as the regulation of the pressure ' s changing in the soil located on the front side of the sunk well foundation
在三維有限元計算中，對不同工況（沉井充填、錨體澆築、主纜架設、箱梁吊裝、橋面鋪裝以及通車運營）下的施工過程作了模擬，全面揭示了各工況下錨碇沉井基礎與地基土的變形變位規律，著重分析了影響散索鞍水平位移的因素以及不同工況下沉井前測地基土水平向抗力變化規律，並提出了不同深度地基土水平向抗力與水平位移間的擬合關系。Construction technique of asphalt paving on steel box girder deck
