Abstract:
The thesis concerns analysis of the stress-seepage coupling in fractured rock mass and its application on dams. The thesis is composed of 5 chapters. The first chapter presents a literature review on researches conducted on fractured rock mass and on seepagestress coupling in fractured rock with a particular focus on numerical modeling. The second chapter concerns the formulation of the composite element method for fractured rock mass. It presents the composite element method for stress and seepage problems. The third chapter concerns the formulation of the composite element for fractured rock mass considering seepage- stress coupling. After the mathematical formulation, it presents the numerical implementation of the composite element and its performances under both normal and shearing stress states. The 4th chapter presents analysis of the seepage-stress coupling for fractured rock mass with drainage holes. The numerical model is validated by its comparison to the convention al finite element method. The last chapter presents the use ofthe composite element for the analysis of the Xiaowan arch dam with complex fractured rock mass. The later contains three sets of fractures and drainage holes. This example shows the advantage and performances of the composite element for the analysis of complex projects.
