水质简分析试验过程解析及数据审核

Analysis and data validation of simple analysis test for water quality in geological survey of hydropower engineering

在水利水电工程中,大部分构筑物由混凝土或钢筋混凝土构成,其中有部分构筑体反复、长期或永久与环境水、土接触。为保证构筑物的长久、安全运行,需提前对环境水、土的化学分析,来判断其是否对混凝土或钢筋存在潜在危害,以便工程技术人员在设计或施工时采取防范措施。因此,水质简分析试验是工程地质勘察项目中的一个重要内容。要做好水质简分析试验,获得准确的试验数据,不仅需准确地运用相应的试验规程、检验合格的试验仪器,还需熟练掌握试验的原理。依据NB/T35052—2015《水电工程地质勘察水质分析规程》,介绍了水电工程水质简分析中关键的试验原理。结合实际工程项目中的试验数据,根据水化学的基本原理,参考相关文献,验证了数据的合理性。

In water conservancy and hydropower projects,chemical analysis of environmental water and soil is used to determine whether there is potential harm to concrete or steel bars,so that engineering technicians can take preventive measures during design or construction.Therefore,the water quality simple analysis test is an important content in engineering geological survey projects.In order to do a good job of water quality analysis test and obtain accurate test data,it is not only necessary to accurately use the corresponding test procedures and qualified test instruments,but also need to master the principle of the test.This paper introduces the key test principles in the water quality analysis of hydropower engineering according to the Code for Water Quality Analysis of Geological Investigation of Hydropower Engineering(NB/T35052—2015).At the same time,combining with the experimental data in the actual project,according to the basic principles of water chemistry,and referring to relevant information,the rationality of the data is verified.
