On the basis of analyzing effect of prestressed tendon layout on internal force and thrust at springer, the principle of prestressed iendon layout for three - span prestressed concrete deck arch bridge is illustrated
摘要在分析預應力布置位置對三跨上承式拱橋內力和拱腳推力影響的基礎上，闡明了該類橋型預應力筋的布置原則。 -
In this paper, the best reinforcement scheme, which was found by nerve network and genetic algorithm from serval reinforcement schemes, was applied to strengthen a prestressed concrete continuous rigid fame bridge with many quanlity faults, such as excess fall deflection of the main span deck > serious web slop crack existing between main pier abutment and one fourth span, and very poor mud jacking quanlity in the prestressing tendon tubs
本文針對某預應力混凝土連續剛構橋所存在的實際問題：如主橋橋面下撓度過大；主墩和四分之一跨徑處均存在較嚴重的腹板斜裂縫；預應力管道壓漿質量較差等。提出了幾種加固方案，並用神經網路和遺傳演算法進一步優化出了較佳的加固方案，進行了加固前後效果對比分析。 -
Combined with that the influence of the prestressed tendon layout on mechanics characteristic of three - span prestressed concrete deck arch bridge is taken into account in these methods, and demand of internal force and displacement in design is satisfied by using upward and downward eccentric layout of prestressed tendon
這些設計法針對該類橋型的特點，利用在拱頂梁中分別布置一定數量的上下偏心的預應力筋來優化結構的內力和滿足各部分的位移限制要求。
