水口水电站坝基析出物的成因解析

The Analysis on Precipitate of Dam Base for Shuikou Hydropower Station

从水口水电站大坝的安检中发现,坝基灌浆廊道、排水廊道部分排水孔出现黄色、白色等析出物。本文从工程地质及水文地质条件着手,经过大量的统计分析、取水样及析出物样进行试验,结合坝基的构造分布,总结了析出物的成因、形成机制及其对坝基的影响,为评价坝基的安全性提供了依据。

Security from the outlet of Dam Base. for Shuikou Hydropower Station was found that the dam base grouting gallery, part of the drainage corridor drainage holes a yellow, white and other precipitates. This article from the engineering geological and hydrogeological conditions to proceed, after a lot of statistical analysis, water samples and test samples precipitates, combined with the distribution of the structure of the dam base, summed up the causes of precipitates, formation mechanism and its impact on the foundation for the evaluation of the dam base the security provided.
