盐渍土地区钢筋混凝土排水管道腐蚀研究

Research on the corrosion of RC drain-pipes in the salty soil zone

西北盐渍土地区的钢筋混凝土排水管道普遍存在腐蚀现象,影响城市排水系统的正常运行,甚至造成路面塌陷。以安西县钢筋混凝土排水管腐蚀为例,研究了盐渍土地区钢筋混凝土排水管道的腐蚀原因,初步探讨了钢筋混凝土腐蚀机理。

The corrosion phenomena of RC drain-pipes is a commonplace in the salted soil zone in northwestern China. It has the effects on the function of municipal drainage systems, and even resuits in the roads＇ surface collapse. Anxi County town is cited here to research the reasons of the RC drain-pipes corrosion in the saline areas and preliminarily discuss the erosion mechanism.
