摘要
随着我国基础设施的不断建设,公路里程不断增长,公路桥梁总数超过100万座,大量桥梁进入养护-检测-维修处置-养护的循环阶段,定期检测作为公路桥梁养护维修的重要依据,其检测结果直接影响养护管理部门的决策.针对简支转连续预应力小箱梁在定期检测过程中遇到的梁体腹板竖向裂缝、钢筋锈蚀,挡块病害及台背排水状况病害,提出 自己的理解与建议,供检测及养护工作者参考借鉴.
Abstract
With the continuous construction of China's infrastructure,highway mileage is growing,and the total number of highway bridges is over one million,with amounts of bridges entering the cycle of curing-detection-maintenance-curing.Periodic detection is a crucial basis for the curing and maintenance of highway bridges,and its results directly affect the decision-making of the maintenance management department.Focusing on the detected diseases of simply supported to continuously prestressed small box girders such as vertical cracks in girder webs,bar corrosions,block diseases,and abutment drainage conditions in the periodic detection,this paper proposed its understanding and suggestions,hoping to provide a reference for detection and maintenance worker.
