摘要
Atay水电站二级坝左岸堆石坝段及上坝公路段覆盖层岩性为粉质黏土混碎石、块石,经综合分析覆盖层帷幕灌浆现场生产性试验成果,提出了防渗帷幕设计方案并付诸实施,经三年多时间的运行,证明覆盖层的防渗设计是成功的。
The overburden layers of the rock-fill dam section on the left bank and of dam abutment of the second stage dam of Atay Hydropower Project consist of silty clay sandwiched with debris and rock block. According to the comprehensive analysis of the productive test results of site overburden curtain grouting, an impervious curtain design scheme is proposed and put into implementation. After operation of more than three years, the impervious design of overburden layer is proved to be successful.
