【摘要】：桥梁在道路交通中扮演着重要的作用,随着交通量的不断增加,重载车辆的不断增多,加上桥梁在运营过程中的日渐老化以及环境的影响,导致桥梁结构出现不同程度的缺陷和损伤,使其难以适应当今交通高速发展的需要。因此,如何检测现役桥梁的承载能力和安全性,评估结构物的损伤程度,并采取经济合理的维修加固措施已显得非常必要。针对这种情况,结合已建现役桥梁,从检测、评估到加固本文开展了以下内容： 1.讨论国内外桥梁检测、评估及加固的研究现状,总结既有检测加固理论；结合本文工程实例,说明了桥梁检测评估与加固的目的和意义。 2.以实桥为例,详细介绍其检测内容和方法,根据检测结果对该桥进行分析评估,为维修加固提供依据。 3.以检测结果为依据,介绍了加固的方法,并对加固进行分析,评定了实桥的加固效果；对比加固前后检测结果,验证该桥加固方法的合理性。为以后类似工程提供依据。
[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.
