【摘要】：伴随社会经济的迅速发展，交通建设重要性日益凸显，其中桥梁扮演着至关重要的角色。但许多桥梁逐渐不能满足当前承受荷载的需要，如车辆超重超载，，或是撞击事故，又或者气候和自然灾害等因素所导致。桥梁承载力的降低，将威胁到公众的生命财产安全，因此对桥梁进行结构检测与评估，能及时掌握桥梁状况，评估其承载能力及时实施相应加固处理措施，保障桥梁使用安全与畅通。除此之外还能收集到相关数据，为同类工作提供应用参考与研究。为此，本文将从以下几个方面的工作进行展开：（1）以某在役桥梁为例，对其进行外观尺寸、外观结构、无损检测、静载试验等方面的检测以及相应的承载力检算。（2）通过对检测数据的分析，得出该在役桥梁结构检测的评估结果，并针对评估结果提出相应的加固建议。为今后相关桥梁进行结构检测和评估提供依据和参考。
[Abstract]:With the rapid development of social economy, the importance of traffic construction is increasingly prominent, in which bridge plays a vital role. However, many bridges can not meet the needs of the current load, such as overloaded vehicles, or impact accidents, or weather and natural disasters and other factors. The reduction of the bearing capacity of the bridge will threaten the safety of public life and property. Therefore, the bridge can be inspected and evaluated in time to grasp the status of the bridge and evaluate its bearing capacity to carry out the corresponding reinforcement measures in time. To ensure the safety and smooth operation of bridges. In addition, relevant data can be collected to provide reference and research for similar work. To this end, this paper will start from the following areas of work: Taking a bridge in service as an example, the external dimensions, appearance structure, nondestructive testing, static load test and the corresponding bearing capacity checking are carried out. 2) through the analysis of the test data, the evaluation results of the existing bridge structure are obtained, and the corresponding reinforcement suggestions are put forward in the light of the evaluation results. It provides the basis and reference for the bridge structure detection and evaluation in the future.
