Technical Note


Grouting is a common method of sealing rock and repairing concrete structures (Turkmen 2003; Butron et al. 2010; Hoien and Nilson 2013; Lim et al. 2013; Bras et al. 2013), and there are many examples of its application to the engineering of dam foundation improvement (Rafi 2010; Saeidi et al. 2013; Rostami Barani et al. 2014). Determining a need for grouting is a main concern in dam foundation improvement (Deere 1982; Ewert 1985). A useful design tool for ground treatment must be able to predict both zones of low water take and low grout take. Our approach is to use the degree of water-bearing structures of the rock fracture to produce reliable zoning map of the dam foundations. For this purpose, the database of the grouting works at Sumbar dam was analyzed. The main objective is to produce a criterion to be used during grouting and capable of a reasonable estimation of the expected sealing through various ground conditions. A systemic statistical analysis to assess the...
