摘要
利用土样较水样取样操作更简便、腐蚀介质扰动更小的特点,通过理论分析及试验研究,建立地下水、土腐蚀介质的相关关系,基于地下水、土腐蚀介质相关性,提出了一种地下水腐蚀评价新方法。介绍了新方法的主要操作步骤及流程图。新方法的关键步骤是首先获取含水层地下水、土的相关系数λ(^(*)),然后以钻孔取土样进行易溶盐分析代替钻孔取地下水样简分析,再将土测试成果换算为水质成果数据,最后进行地下水腐蚀性评价。通过工程实例的腐蚀性评价,分析表明了该方法的正确性和有效性,具有推广意义。
Utilizing the characteristics of easier operation of soil samples and less disturbance of corrosive media than water samples,theoretical analysis and experimental research are used to establish the correlation between groundwater and soil corrosive media.Based on the correlation between groundwater and soil corrosive media,a new method for groundwater corrosion evaluation is proposed.The main operation steps and flow chart of the new method are introduced.The key step of the new method is to first obtain the correlation coefficientλ(^(*))of the groundwater and soil in the aquifer;then use the borehole soil sample to perform soluble salt analysis instead of the simple analysis of the groundwater sample from the borehole;then convert the soil test results into water quality data,and finally conduct groundwater corrosivity evaluation.Through the corrosiveness evaluation of engineering examples,the analysis shows the correctness and effectiveness of the method,and it has promotion significance.
