Abstract

Generally tectonic forces cause folding, faulting, and cracking in rocks. These discontinues create void which seepage and consume water. Grouting in the rock by filling joint and cracks controls seepage and increases rock strength. Amand earth fill dam in North Khorasan Province on fractured Sarcheshmeh gray shales which affected by tectonic forces in depth and erosion by climate on surface. These fractures play an important role in grouting. This paper evaluates engineering characteristics of fractures such as spacing, length and joint filling material, and thus effects on the grouting curtain
