| 摘 要： | 把块裂结构岩质边坡看作拟连续介质与块裂介质广义双重介质，运用现代分形理论，建立了1～2级主干裂隙分形网络，并根据两类介质接触处水头相等及节点流量相等建立了合理的块裂结构边坡三维渗流模型，给出了有限元解法，模拟了三峡工程的蓄水位致175m时边坡渗流场的变化，在应用上有较好的可靠性与广泛性。

| Abstract: | The authers set up reasonable seepage model which simulates the change of the seepage flow field within the slope when the water level is up to 175m. The seepage model of block -fractureslope is studied.In order to make the model more reasonable and more effective in application, the authers creat the seepage model of double porosity media including discrete media and equivalent continuum. Based on the relationship of fracture and engineering mass.1-2 grade fracture net is considered. According to the equivalent of pressure of two kinds of media,three-dimension seepage model is created by using modern fracture theory and its FEM solution is given. |
