Stress Field of the Three Gorges Based on Fluid-Solid Coupling Simulation
Abstract In this paper, we use the Rhino software to get the topography of the Three Gorges reservoir and facilitate the topographic data to build the model in FLAC3D. The model consists of 6 layers with different parameters of the rock. After setting the mode of the calculation in FLAC3D, we get the results of the reservoir under the water level of 145 m and 175 m, based on the fluid-solid coupling theory. According to the results, the influence of pore water pressure within 3 km from surface to underground should not be ignored.
