摘　　要：以工程结构可靠性为核心,介绍了国内外超重荷载桥梁的安全性评估研究动态,并对其主要的安全性评估模型进行介绍,以14台电力机械设备的运输过程所经过的沿线5座桥梁为例,对该桥梁的受力特点进行分析,并对其安全性进行合理评估,在此基础上提出相应的桥梁临时加固方法,从而提高超重荷载下桥梁的自身安全性能,确保大型机械设备的行驶通畅。Taking the reliability of engineering structure as the core,this paper introduces the research trends of safety assessment of over loaded bridges at home and abroad,and introduces the main safety assessment models.Taking 5 bridges along the line that 14 electric mechanical equipment pass through in the transportation process as an example,it analyzes the stress characteristics of the bridge,and makes a reasonable assessment of its safety.On this basis,the corresponding temporary reinforcement method of the bridge is proposed,so as to improve the safety performance of the bridge under the overweight load and ensure the smooth driving of the large mechanical equipment.
