Abstract

Various methods provided for reducing the seepage of water from the dam foundation and abutments that the most common techniques is Curtain Grouting. Quality and efficiency of Grouting operation depend on various factors such as ABSORPTION, grout properties and grouting Pressure. One of the most effective parameter is the grouting pressure, because of overpressure, causing hydraulic fracturing inrock mass and low Grouting pressure, causing partial stay of the operation and the site is not completely sealed. So far, different comments, equations, tables and charts have been provided to calculate the necessary pressure in grouting operation. In this paper, has been investigate the effect of grouting pressure in difference stag of Seymareh dam. For this purpose, the grouting pressure is Calculated based on the analytical equations and compared with the actual pressures and finaly the best Model is selected. The results show that Groundy and Zaruba equations (with horizontal joints) prepare more accurate estimates of the grouting pressure than others. Also, new Equation is developed to calculate of grouting pressure as a function of Lug eon number that is able to calculate the acceptable grout pressure.
