淮水北调某输水管线土壤腐蚀性评价研究

Soil Corrosive Evaluation Study on a Huai Shui North Water-Transmission Pipeline

土对钢结构具有腐蚀性,土对钢结构的腐蚀性评价是根据设计任务要求,依据相关规范并考虑钢结构埋置条件等选择合适的测试项目来确定的。本文以某输水管线工程实例,通过选择(视)电阻率、极化电流密度、PH值等合适的项目测试,来研究评价土壤对钢结构的腐蚀性,为管道防腐提供依据。

Soil corrosive to steel structure,evaluation of soil corrosion on the steel structural is in accordance with the requirements of design task,on the basis of the relevant specification and steel structure embedment conditions such as choosing appropriate test project. Based on a water pipeline project as an example,by selecting the resistivity（ apparent）,polarization current density,PH value,such as the appropriate test of the project,to study the evaluation of soil corrosion on the steel structural,provide the basis for pipeline corrosion protection.
