撒融雪剂除冰引起的钢筋锈蚀是北方跨河桥梁结构破坏的重要原因。通过对北京市通州区的一些跨河桥梁的氯化物含量的测试,初步探讨了造成该地区桥梁钢筋锈蚀的主要原因,并从设计方面提出解决问题的办法。
Reinforcing steel deicing caused by snowmelt corrosion is an important reason for the destruction of the bridge structure in the north. Based on the test of chloride content in some bridge across the river in Tongzhou district of Beijing, the paper mainly discusses the main reasons that lead to the corrosion of steel bars in bridges in this area and puts forward some solutions to the problems from the design aspect.
