Study on Improvement of Dam Foundation by Grouting Treatment

Autor: Kohkichi Kikuchi, Yoshitada Mito, Tetsuo Igari

Publikováno v: Journal of the Society of Materials Science, Japan. 47:515-520

The purpose of consolidation grouting for dam foundation is to improve the permeability and mechanical properties of rock masses. For permeability, the grouting effect is usually confirmed by the permeability test at check holes. But for the change o
