摘要
Abstract
In order to study the stability of dam foundation and the duration of seepage control curtain, the chemical composition, microstructure and phase composition of all types precipitates in different parts of the corridor in a hydropower station, as well as the rock-mineral and water quality are analyzed. The results show that the precipitates are the hydration of bedrock and cement for seepage control curtain and deposit from drainage holes, the flocs in downstream drainage channel are micro-organisms and pale blue gelatinous precipitates are acrylate gel precipitation substances. The precipitates are the production of water chemical suffusion, and there are microbial environmental in the foundation. Thus, the physicochemical interaction between water-rock-dam would affect dam foundation in the role of chemical suffosion and micro-organisms. The precipitates of dam foundation and the quality of water should be regularly monitored.关键词
