Abstract

Grouting proceedings are one of the ways to decrease permeability and to increase the resistance and fixation of jointed rocks in construction area. One of the following issues in this operation is to estimate the PENETRATING RADIUS and the amount of cement grout that has been introduced as the main parameters of grouting operation. The analytical and numerical methods have been used to estimate these parameters. In analytical method 5 models were presented. In numerical modeling the profile of rock block, bore and grouted cleft were designed by UDEC software and then grout features and final pressure of grouting were entered. To investigate the above models, as a case study, the geotechnical data and grouting information of Seymareh site dam were used.The results of numerical and analytical modeling were compared with the real corrode (recorded in site) and analyzed. The computations show that in analytical modeling, the first model (Janson) can provide a better and more suitable assessment from the amount of injected grout in comparison with other models. The results of numerical modeling have acceptable accordance with the results of analytical models. But totally, numerical modeling can provide better assessment in the amount of injected grout. However, numerical computations are time taking and not easy to do in field because of the lack of calculating facilities during the operation, so, the use of analytical models, due to some simplifications, seems to be more practical during the grouting operation.
