【摘要】：橋梁在道路交通中扮演著重要的作用,隨著交通量的不斷增加,重載車輛的不斷增多,加上橋梁在運營過程中的日漸老化以及環(huán)境的影響,導致橋梁結(jié)構(gòu)出現(xiàn)不同程度的缺陷和損傷,使其難以適應當今交通高速發(fā)展的需要。因此,如何檢測現(xiàn)役橋梁的承載能力和安全性,評估結(jié)構(gòu)物的損傷程度,并采取經(jīng)濟合理的維修加固措施已顯得非常必要。針對這種情況,結(jié)合已建現(xiàn)役橋梁,從檢測、評估到加固本文開展了以下內(nèi)容： 1.討論國內(nèi)外橋梁檢測、評估及加固的研究現(xiàn)狀,總結(jié)既有檢測加固理論；結(jié)合本文工程實例,說明了橋梁檢測評估與加固的目的和意義。 2.以實橋為例,詳細介紹其檢測內(nèi)容和方法,根據(jù)檢測結(jié)果對該橋進行分析評估,為維修加固提供依據(jù)。 3.以檢測結(jié)果為依據(jù),介紹了加固的方法,并對加固進行分析,評定了實橋的加固效果；對比加固前后檢測結(jié)果,驗證該橋加固方法的合理性。為以后類似工程提供依據(jù)。
[Abstract]:Bridges play an important role in road traffic. With the increasing of traffic volume, the increasing of heavy vehicles, the aging of bridges and the impact of environment. The bridge structure has different defects and injuries, which makes it difficult to meet the needs of high-speed traffic development. Therefore, it is necessary to measure the bearing capacity and safety of existing bridges, to evaluate the damage degree of structures, and to take economical and reasonable maintenance and reinforcement measures. In view of this situation, combined with the existing bridges, from the detection, evaluation to reinforcement of this paper, the following contents are carried out: 1. This paper discusses the present research situation of bridge detection, evaluation and reinforcement at home and abroad, summarizes the existing inspection and reinforcement theory, and explains the purpose and significance of bridge detection, evaluation and reinforcement with an engineering example in this paper. 2. Taking the real bridge as an example, the contents and methods of its detection are introduced in detail, and the bridge is analyzed and evaluated according to the test results, which provides the basis for maintenance and reinforcement. 3. Based on the test results, the reinforcement method is introduced, and the reinforcement effect is evaluated by analyzing the reinforcement method, and the rationality of the reinforcement method is verified by comparing the test results before and after reinforcement. To provide the basis for similar projects in the future.
