Abstract

Grouting is one of the most popular methods used to control water leakage in fill dam constructions. Geological and geotechnical properties of the rock/soil to be grouted are important parameters influencing the design of the grouting. In this study, geotechnical properties of Dalaman-Akköprü Dam’s base rock and the grouting procedure have been investigated in view of their suitability to grouting. In the study, detailed investigations of the foundation injection applications were made into the main rock, the reasons and types of application are made. The materials used in grouting and the grouting pressures are investigated at site and the obtained results are presented. The improvement study and application type is evaluated and background information on different applications of grouting is presented.

Key words: Grouting, dam, Akköprü Dam, imperviousness.
