Popis:	Although foundation grouting for dams is always performed as one of the most important foundation treatment works, the prediction of necessary cement takes is considered to be difficult. In this paper, several dam grouting projects of granitic rock foundations which have similar specifications have been reviewed, and the results indicate that there exists good correlations between Lugeon value and unit cement takes in grouting procedure.In field practice, Lugeon value is obtained by using the water pressure tests prior to the grout injection, and the value is used for determining the details of further grouting works. The value suggests the properties of rock foundations, but it has been considered to be irrespective of cement grout takes. The study of this paper concludes however, that total amount of grout takes can be predicted from the initial Lugeon value macroscopically.
