Discussion on the Application of Grouting Technology in Treating Geological Defects of Dam Foundation of Zhidian Reservoir

This paper is a survey reservoir engineering geological defect treatment were simply introduced and summarized, through local strong unloading zones in dam foundation grouting of fissure and cavity cave filling, eliminates the geological defects, to achieve the requirement of the foundation stability, reduce the leakage, the dam foundation rock geological defect treatment has accumulated experience for the future.
