The prestressed continuous beam - arch composite bridges are a special structural system where the horizontal thrust of the arch rib is absorbed by a prestressed tie at deck level. in some cases, this type of structure is preferable because it does n ' t have the large thrust at the spring hi traditional arch bridges and the somewhat large bending moment and shear force in traditional beam bridges. as a result, the performances of the prestressing reinforcement can be efficiently utilized

In light of the simulative research results, three methods are applied to analyze some controversial problems in this kind of structural system ( such as the concrete pouring sequence of continuous ends, the applying sequence of pretensioned force, the removal of the temporary supports, the concrete pouring style of continuous ends, the optimization of constructional reinforcement and prestressed reinforcement ). some important conclusions are drawn : the concrete pouring sequence of continuous ends should be in accordance with the principle of " interval end " ; the removal of temporary supports is also on this principle ( opposite to traditional opinions ). at the same time, other problems such as the shrinkage and creep effects of concrete, the c racking and failure pattern, the optimization of reinforced bars and prestressed bars are also analyzed in detail
在此基礎上，對于目前先簡支后連續結構體系中存在的一些有爭議的問題（如后連續端部澆築和后連續預應力張拉的順序、體系轉換中的臨時支座拆除順序、后連續端部澆築方式、后連續端部的預應力筋及普通鋼筋的優化等） ，我們分別運用三種方法進行了細致的模擬分析、研究，並得出了一些具有重要工程意義的結論：后連續端部的澆築順序和后連續預應力張拉的「隔跨」原則，臨時支座拆除的「隔跨」原則（此前人們一直認為「對稱澆注和對稱張拉」是最為合理的施工工序） ，混凝土的收縮、徐變對先簡支后連續結構體系的影響一般較小等。 -

對于變截面t梁、工字梁、箱梁等常見結構，截面形式復雜，一些部位尺寸較小且密集配筋，如梁頂板，梁底板，預應力管道間，混凝土不可避免的造成不密實導致耐久性降低，而這些問題往往為設計者所忽略。對于新建橋梁混凝土的密實度問題，尤其是新建橋梁關鍵部位的混凝土密實度和耐久性問題，人們研究和關心的較少，這也為橋梁的質量監督控制和使用壽命埋下了隱患。 -
