Study on external water pressure of water conveyance tunnel for the pumped storage power stations in Huizhou City
A 3D numerical model of groundwater flow is established according to the geological conditions.Fractured rock mass is consist of rocks matrix, which is represented using the equivalent continuum model and fracture network,which is described with a discrete-fractured network model. The two models are coupled with continuum groundwater table and flux equilibrium, and solution of coupling model is deducted. The comparison is conducted between the measured and simulated external water pressure, which shows that the coupled model is feasible. Also different drainage schemes are designed and discuss the distribution of external water pressure of the schemes.
