【摘要】：隨著各種橋梁技術的快速發(fā)展,鋼混結合結構在橋梁建設中也被廣泛應用,鋼混結合結構優(yōu)點有:適合跨度大、自身抗扭剛度大、材料強度高、減輕結構自重、加工便利、整體性好、外型輕盈美觀、施工周期短、對施工區(qū)域周圍的環(huán)境影響較小等優(yōu)點。與混凝土結構相對比,鋼混結合結構橋梁能有效減輕橋梁結構自重。隨著國內交通業(yè)的發(fā)展,鋼混結構橋梁在建設實施過程中的推廣將得到普遍應用。鋼錨箱外包混凝土外傾塔柱在應用過程中較少,本論文結合重慶嘉悅大橋施工實踐,主要對鋼錨箱加工,施工安裝定位控制,塔柱施工工藝、外傾塔柱施工控制以及外傾塔柱模板穩(wěn)定計算等施工和技術控制,采取理論計算與實際結合的方式,安全簡便的實現鋼結構與混凝土結構混合斜塔施工,對該體系本文著重介紹了整個混合結構斜塔關鍵技術和施工工藝,以便類似工程予以借鑒。為明確本工程在施工階段實際受力情況,采用工程分析軟件MIDAS,通過建模計算,分析梁體的各項受力性能以及變形情況,并對結果進行分析,查看是否滿足相應要求,以保證工程質量和安全。同時在工程完成后,及時進行橋梁靜動載試驗,通過測量橋梁在規(guī)范中規(guī)定的相應動載作用下的應力應變和撓曲變形情況符合規(guī)范要求。鋼混結構作為橋梁建設中的主要受力結構,其各項技術優(yōu)勢不斷被發(fā)掘,為橋梁事業(yè)的發(fā)展開辟了新的發(fā)展空間,它的出現讓橋梁的建設更靠近了“安全、經濟、使用、美觀”的目標,我們作為未來橋梁事業(yè)的主力軍,我們應該充分認識到鋼混結構的各項優(yōu)勢,去創(chuàng)造橋梁建設的新成就。本文的研究結果對促進鋼錨箱制作與安裝技術的理論完善化、實踐普遍化,同時可為今后同樣形式橋梁的施工積累經驗,豐富橋梁施工的方式。
[Abstract]:With the rapid development of various bridge technology, steel-concrete composite structure is also widely used in bridge construction. The advantages of steel-concrete composite structure are: suitable for large span, large torsional stiffness, high material strength, reduced structural weight, easy processing. It has the advantages of good integrity, light appearance, short construction period and less influence on the surrounding environment of the construction area. Compared with concrete structure, steel-concrete composite bridge can effectively reduce the weight of bridge structure. With the development of domestic transportation industry, the promotion of steel-concrete structure bridges in the process of construction and implementation will be widely used. The external concrete tilting tower column of steel anchor box is less in the application process. This paper combines the construction practice of Chongqing Jiayue Bridge, mainly processes the steel anchor box, the construction installation position control, the tower column construction technology, The construction and technical control of external tilting column construction control and external tilting column formwork stability calculation are adopted to realize the construction of mixed inclined tower of steel structure and concrete structure safely and easily by combining theoretical calculation with practice. This paper mainly introduces the key technology and construction technology of the mixed structure inclined tower, so that similar engineering can be used for reference. In order to make clear the actual force situation of the project in the construction stage, adopt the engineering analysis software midas, through modeling and calculation, analyze the various mechanical properties and deformation of the beam body, and analyze the result, see whether meet the corresponding requirements. To ensure the quality and safety of the project. At the same time, after the completion of the project, the bridge static and dynamic load tests were carried out in time, and the stress, strain and flexural deformation of the bridge under the corresponding dynamic loads specified in the code were measured according to the requirements of the code. As the main force structure in bridge construction, steel-concrete structure has been excavated continuously, which has opened up a new development space for the development of bridge, and its appearance has brought the bridge construction closer to "safety, economy and use." As the main force of bridge construction in the future, we should fully recognize the advantages of steel-concrete structure and create new achievements in bridge construction. The results of this paper can promote the perfection of theory and practice of steel anchor box making and installation technology, at the same time, it can accumulate experience for the same form of bridge construction in the future and enrich the way of bridge construction.
