小半徑彎梁橋中后張有粘結預應力施工問題芻議 -
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。 -
Based on rizhao port bulk grain wharf construction, this paper presents a simple, practical and efficient construction technique of post - tensioned pre - stressing concrete beam and beam - slab
摘要以日照港散糧碼頭施工為例，介紹一項簡單、實用、高效的后張預應力梁及梁板的施工工藝。 -
At the last of this paper, we summarized the deficiencies of simulating pre - stressing anchor and proposed the new and accurate simulating method which is given up the traditional tow points applied forces and applied a point reverse forces, made beam element simulate the anchor bolt, made interface element simulate concrete. in addition, we proposed two simulating methods applied on flock anchors which improved on considering the contribution of anchors " tangent - orientation stiff. one is post - stressing offset method ; the other is anchor element method
另外，本文還提出了兩種改進原有群錨模擬中沒有考慮錨索限制變形的側向剛度貢獻的方法，即后續張拉補償法和錨索單元法，通過平面直線型滑動破壞中這兩種方法與傳統群錨的兩點集中力法的比較、分析，表明這兩種方法的結果與實際情況較為相符。
