中文摘要：
在建松花江公路大桥位于东北寒冷地区,其易受冻融循环作用的影响,因此,对大桥所处地区的气温、湿度、降雪量、冰冻时间、年冻融循环次数等进行全面的调查和测试是十分必要的。为之,对大桥的腐蚀环境进行了详细调查,对大桥环境中的侵蚀性气体进行了检测,对大桥区域中的大气降水及松花江水质进行了分析,并对河床泥土侵蚀性离子进行了综合测试。调查和研究为松花江大桥的耐久性评估提供了基础数据。
英文摘要：
Songhua River Highway Bridge is located in the northeast cold areas of China,which is affected by the freeze-thaw cycles vulnerably.Therefore,the temperature,humidity,snowfall,freezing time,freezing and thawing cycles and so on in the area were comprehensively investigated and tested.In addition,the corrosive environment in the area where the bridge is located were investigated in detail,including the erosion gas detection,the atmospheric precipitation analysis and water quality analysis of Songhua River,and the river bed＇s soil erosion ion test.The investigation and research could provide basic data for the durability evaluation of the bridge.
