Abstract

Abstract

Grouting is a common measure for leakage control in dam rock mass. , Currently the physical grouting test is used to determine the parameters such as grouting ratio and pitch. It must spend a lot of time and effort. This paper develops a 3-dimesional numerical simulation test of grouting seepage for rapid determining grouting schemes. It uses a dam site with known geological conditions and analysis of rock leakage. It simulates the migration regularity of groundwater water before store water in the reservoir. The simulated results are compared with actual drilling data and ground water migration patterns in flat adit. The assumption of groundwater migration rule is also compared. It then simulates the groundwater reservoir migration regularity of groundwater, simulates and understands migration regularity of groundwater, and the direction of migration. The preliminary judgment is done according to the actual situation of groundwater migration direction. Finally, numerical simulation determines the certain proportion of slurry grouting for grouting quantity and the situation of the actual grouting test results. The results show that the numerical simulation test can establish the relationship between mix design of slurry grouting and the effect of grounting. This relationship can be used for quick selection of the mix design in similar proportions.
