摘　　要：高频度超限车辆运输对于沿线桥梁结构的结构性能以及使用性能会产生不利的影响,对于桥梁结构安全过程控制提出了更高的要求。基于高频度超限车辆运输的特点,以桥梁结构安全控制为目标,结合轨交16号线现场检测、监测方法及手段,提出以运输前关键病害检测和承载能力检算评估,运输过程中关键桥梁监测的全过程控制方法。该方法可有效评估和控制沿线桥梁的技术状况,为同类运输工作开展提供有效的管控手段,具有重要的实践应用价值。High-frequency overloaded vehicles could be adversely affecting structure performance of bridges,which request more measures for the security control of bridges.Based on Characteristics of the high-frequency overloaded vehicles,and test method used in the Shanghai Line 16 project,the whole process control method consisting of pre-inspection and monitoring during the process has been developed,which can evaluate and control the technical conditions of bridge effectively.The method has important practical application value,and can be used widely in the same kind of projects.
