盐渍土地区输电线路钢结构腐蚀性动态调整与应用研究

Study on Dynamic Adjustment and Application of Corrosion of Transmission Line Steel Structure in Saline Soil Area

近年来,随着输电线路在盐渍土地区的广泛建设,建筑材料的腐蚀问题层出不穷。目前,有关盐渍土地区输电线路建筑材料腐蚀性动态调整问题的研究尚属空白。基于此,将地基土湿度、盐量和扰动条件等与土壤电阻率结合起来,探讨腐蚀性等级的影响因素,并对这些因素可能造成的腐蚀性等级的动态调整做出定量的研究分析,为盐渍土地区钢结构防护措施的选择提供依据,保证后续防护工作的有效进行。

In recent years,with the extensive construction of transmission lines in saline land areas,the corrosion problems of building materials emerge endlessly.At present,the research on the dynamic adjustment of the corrosivity of transmission line building materials in saline soil areas is still blank.Based on this,the paper combines the foundation soil humidity,salt content and disturbance conditions with the soil resistivity,discusses the influencing factors of the corrosivity grade,and makes quantitative research and analysis on the dynamic adjustment of the corrosivity grade that may be caused by these factors,so as to provide a basis for the selection of protective measures for steel structures in saline soil areas,and ensure the effective implementation of subsequent protective work.
