Abstract

Azadi rockfill dam is located on Zemkan River in the west of Iran. There is a deep permeable zone in the rock mass of the foundation. So, the grouting galleries are considered in two different levels to sealing the foundation successfully. The lower gallery is more critical and is studied in this paper. The critical sections that are studied are at the deepest zone of left abutment, deepest zone of right abutment and the middle part of the dam axis. In this paper, the stability conditions of the mentioned sections are studied using different methods including empirical, analytical and numerical (FDM and DEM). The groundwater condition has been considered in DEM analysis and finally, the suitable support systems are suggested based on coupled hydromechanical numerical modeling.

Hydro-Mechanical Numerical Analysis of Grouting Galleries in Azadi Rockfill Dam

New York, New York

Azadi rockfill dam is located on Zemkan River in the west of Iran. There is a deep permeable zone in the rock mass of the foundation. So, the grouting galleries are considered in two different levels to sealing the foundation successfully. The lower gallery is more critical and is studied in this paper. The critical sections that are studied are at the deepest zone of left abutment, deepest zone of right abutment and the middle part of the dam axis. In this paper, the stability conditions of the mentioned sections are studied using different methods including empirical, analytical and numerical (FDM and DEM). The groundwater condition has been considered in DEM analysis and finally, the suitable support systems are suggested based on coupled hydromechanical numerical modeling.
