夹岩水利枢纽面板堆石坝工程帷幕灌浆试验成果分析及其应用

Analysis and Application of Curtain Grouting Test Results in Rockfill Dam with Face Slab of Jiayan Hydro Project

以夹岩水利枢纽面板堆石坝工程为例,主要介绍在泥质粉砂地质条件下进行帷幕灌浆生产性试验过程,对孔位布置、灌浆材料、施工工艺、特殊情况处理及试验成果进行分析,并提出最终帷幕灌浆施工设计方案及其施工参数优化建议,为后期坝段及其他部位的帷幕灌浆提供了有效参考依据。

Taking the rockfill dam with face slab project of Jiayan Hydro Project as an example,this paper mainly introduces the productive test process of curtain grouting under the geological conditions of argillaceous silt,analyzes the hole layout,grouting material,construction technology,special treatment and test results,and puts forward the final curtain grouting construction design scheme and its construction parameter optimization suggestion,which provides an effective reference for the curtain grouting of the later dam section and other parts.
