  4. Temperature field and stress field of prestressed concrete box - girder bridge

    預應力混凝土箱梁橋的溫度場和應力場
  5. With the development of material science and transportation, thin - wall box girder ( including steel girder and prestressed concrete girder ) is used wildly in modern engineering of bridge, but shear - lag problem is arising accordingly, the result it takes can not be ignored, especially broad and low box girder

    隨著材料科學和交通事業的發展，薄壁箱形梁（包括鋼箱梁、預應力混凝土箱梁）在現代橋梁工程中得到了廣泛地運用，但隨之而來是剪力滯后問題相當突出，特別是寬扁箱梁剪力滯效應不容忽視。
  6. Especially the bridge engineering has to be concerned with high, new and difficult technologies. new technologies firstly adopted are post - tensioned prestressed concrete simply - supported box girder, assembly two - way prestressed concrete simply - supported t - girder, reinforced concrete continuous rigid frame, and steel - concrete composite continuous girder. all these have formed a series of new bridge structures taking prestressed concrete simply - supported box girder as main feature

    由於秦沈客運專線的特殊技術要求，在鐵路建設史上首次採用了后張法預應力混凝土箱形簡支梁、裝配式雙向預應力混凝土t形簡支梁、鋼筋混凝土剛構連續梁、鋼與混凝土結合連續梁等橋跨結構，形成了以預應力簡支箱梁橋跨結構為主要特徵的一系列橋梁新結構。
  7. In recent years, during the detection of the established reinforced concrete or the prestressed concrete box girder bridges etc. the large structures, we can find that the concrete in particular structural positions such as the anchorage zones of prestressed reinforcement with dense reinforcement, the prestressed pipe in which the space of reinforcement or the thickness of concrete cover is small, the top and bottom flange of box girder and so on has brought great difficulty to concrete construction because of the small size and densely - packed reinforcement

    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。
