摘要

引用本文

摘要：首先根據某地區近年的氣象資料和有關規范，計算出該地區混凝土砌體結構的組合溫差。在此基礎上建立了某試點建筑結構足尺的三維有限元模型，對其進行溫度效應有限元分析，考慮不同的構造措施，得到了各種構造措施下砌體建筑關鍵部位的應力和位移等數據。最后對結果進行分析和比較得出，在頂層墻體與屋頂間設置溫度分隔縫是控制裂縫最有效的措施。為該地區混凝土砌體結構裂縫的控制提供了有效的理論依據。

摘要：通過試驗，研究開發了一種集優越力學性能和良好耐久性能于一體，既能滿足橋面鋪裝層的功能要求又能解決橋面鋪裝層早期破壞和耐久性低問題的新型橋面鋪裝材料——混雜纖維混凝土。引入聚丙烯仿鋼絲粗纖維來代替部分鋼纖維，既可降低工程造價又可降低鋪裝層的自重，其對纖維混凝土力學性能及耐久性能的提高可和鋼纖維媲美，甚至比摻單鋼纖維更高。在混雜纖維混凝土中摻入膨脹劑和引氣劑，與素混凝土和單一纖維混凝土相比，抗彎強度、彎曲韌性明顯改善，抗滲等級提高到29級，抗凍融性能也有一定程度的提高，耐久性顯示出明顯的優勢，是橋面鋪裝材料的理想選擇。 Absract: A set of new bridge deck pavement materials - hybrid fiber reinforced concrete is studied and developed by experiment, which have excellent mechanical properties and good durability, and can meet the functional requirements of bridge deck pavement and resovle early damage and the problem of low durability. Not only the project's cost but also the weight of pavement layer can be reduced by polypropylene imitation steel wire fiber insteading of parts of steel fiber. Furthermore, the mechanical properties and durability of hybrid fiber reinforced concrete can be improved even than steel fibers. By admixturing with expansive agent and air-entraining agent, compared with steel fiber reinforced concrete and plain concrete, the composites has significantly improved the flexural strength and toughness, and the permeability grade is increased to 29. In addition, anti-freeze-thaw performance has also been a certain increased. The durability demonstrates a significant advantage and the composites will be an ideal choice for bridge deck pavement materials.
