Simulation of the Seepage Field in the Danjiangkou Reservoir Area
According to the geological conditions of the Danjiangkou reservoir, the computational model was set up considering fracture zones and the changing along the depth of mechanical properties of rock. Adopting this model, the seepage field of the reservoir area was simulated for long time, which shows that: 1) The medium and small earthquakes in the reservoir area were induced mainly by reservoir water seepage since phaseⅠimpoundment; 2) A series of medium earthquake would be induced in the fracture zones of reservoir bottom and around the reservoir bank in the depth of 5km about in a month of phaseⅡ impoundment; 3) A series of small earthquakes would be induced in the fracture zones in the depth of 12km to 16km at the same period.
