摘要
渗流分析是水电工程中一项重要的研究内容。大坝周围岩体的渗流通道大多为裂隙网络 ,用连续介质渗流模型难以解决这一问题。针对岩体主干裂隙网络渗流特征 ,建立了岩体三维主干裂隙网络渗流模型 ,运用有限元数值方法 ,结合算例分析了坝基岩体主干裂隙网络渗流问题。理论解与有限元解的比较结果表明 。
Seepage analysis is an important item for hydropower engineering. Much of seepage paths is fracture network in rock mass surrounding dam. It is difficult to solve this seepage problem in fracture network by using continuum model. In terms of seepage characteristic in fracture network of rock mass, three dimensional seepage model in main fracture network of rock mass is constructed. The finite element method in combination with calculation examples is used to analyse three dimensional seepage problems in main fracture network of dam foundation. The results of comparison of theoretical solution with finite element solution indicate that three dimensional seepage model in main fracture network of rock mass and the finite element numerical approach are effective and available.
