  • According to the difference of growing scales of fractures in rocks,fractured domains can be divided into continuous and discrete domains.Different mathematical models of groundwater movement are used in the continuous and discrete domain.The problem can be solved by domain decomposition algorithm.An equivalent continuum medium model is applied to the continuous domain and a stochastic fractured network model to the discrete domain.Hence,according to the continuous conditions of groundwater table and flux in the common boundary of the two domains,the coupled models can be solved.Furthermore,the coupled model based on the domain decomposition algorithm is applied to simulation of three-dimensional seepage field in the dam site of Jinping hydroelectric power station.Compared the observed results with the calculated groundwater table,the result shows that the coupled model based on the domain decomposition algorithm is effective and can be applied to practical engineering.
