摘要
对采砂船撞击后的勐拉大桥进行应急检查,评估分析其损伤情况.通过精心组织及安排,对桥梁上部结构、下部结构、桥面系进行外观检测,计算分析采砂船撞击力,测量墩柱竖直度,综合评定桥梁技术状况.该桥总体技术状况等级评定为4类,需进行改造或大修,应及时对交通进行管制,如限速、限载,当缺损较严重时应关闭交通.建议进行荷载试验确定桥梁的实际承载能力,来制定处治或加固方案.
In order to investigate and evaluate the damaging impact on Mongla Bridge, emergency examination of the Bridge has been carried out. Through careful organization and arrangement, such as the appearance inspection of superstructure, substructure and bridge deck system, and analysis and calculation of impact force of the dredge, measurement of pier verticality, the technical condition of the bridge is evaluated synthetically. The overall technical status of the bridge is evaluated as fourth categories. And it requires renovation and a timely traffic control, such as rate-limiting and load limit, and the bridge should be closed when the defect is serious. It is suggested that the load test should be carried out to determine the actual bearing capacity of the bridge to formulate the reinforcement scheme.
