红水河流域部分水电站析出物的初步分析

Preliminary Analysis of Precipitates from Some Hydropower Stations in Hongshui River Basin

笔者参照GB/T 176—2017《水泥化学分析方法》对2019—2023年红水河流域的天生桥二级电站、平班水电站、岩滩水电站和乐滩水电站的析出物进行检测,并对析出物主要成分的含量及其变化进行分析,总结出各电站析出物主要成分之间的共性。结果表明:析出物的主要成分为CaO、Fe_(2)O_(3)、SiO_(2),与往年相比,各成分含量变化不大;近5年4个水电站析出物的主要成分都以CaO为主,除个别电站的Fe_(2)O_(3)、SiO_(2)含量较高外,其他成分含量都处在相接近的范围。通过定期检测分析水电站析出物含量,可为采取的工程补强措施提供依据,为大坝安全运行提供技术支持。

The author refers to GB/T 176-2017"Methods for Chemical Analysis of Cement"to detect the precipitates of Tianshengqiao I Hydropower Station,Pingban Hydropower Station,Yantan Hydropower Station and Letan Hydropower Station in Hongshui River Basin from 2019 to 2023,and analyzes the content and change of the main components of the precipitates,and summarizes the commonalities between the main components of the precipitates of each power station.The results show that the main components of the precipitates are CaO,Fe_(2)O_(3)and SiO_(2),and the content of each component does not change much compared with previous years;In the past five years,the main components of the precipitates of the four hydropower stations are mainly Cao.except for the high content of Fe_(2)O_(3) and SiO_(2) in individual hydropower stations,the content of other components is in a similar range.Through regular detection and analysis of the content of precipitates in hydropower stations,it can provide a basis for the engineering reinforcement measures and provide technical support for the safe operation of the dam.
