新疆北部地区盐渍土的腐蚀机理及防治措施

Research of Corrosion Mechanism and Preventive Measures of Saline Soil in XinJiang North-area

通过对北疆地区盐渍土的基本特征分析,探讨了影响盐渍土路基及构筑物病害的因素,主要是气候、地形地貌和水文条件;易溶盐试验结果表明,本地区盐主要以氯(亚氯)盐渍土和中硫酸(亚)盐渍土为主。总结出了两种盐对建筑物及路基的腐蚀和破坏机理,并针对不同的病害机理归纳出了目前两种盐在防治方面所采取的主要措施,并就相应的措施进行了一定的评价,指出目前防治措施多是经验的总结,还需从理论方面做进一步的深入研究。

Through analyzing basic characteristics of saline soil in Beijiang area,factors which generate the diseased of the saline roadbed and structures are discussed,mainly including climatic conditions、topography and hydrologic conditions.The experiment results of soluble salt show that salt in the region is mainly chlorous（dle） saline soil and moderate sulfuric（sulfurous） saline soil.The corrosion and destruction mechanism of two types saline soil on structures and roadbeds is summarized,correspondingly,preventive measures are put out and appraised,pointing out that the current control measures are mostly a summary of experience,further study needed from theory aspects.
