.... It yields a first rough estimation in the whole reservoir by a simple interpolation which is not in equilibrium with the external forces and boundary conditions. From this rough stress field, the inversion aims at finding a physically acceptable stress state (i.e.: in equilibrium with the external forces...

... joints are prepared. The asperity angle of planar and non planar joints are kept as 0°-0° and 15°-15° respectively. These joints are prepared with plaster of Paris and tested under CNS boundary condition. Sample size of joints is kept at 298*298*125 mm, and in between the joints; infill material...

... segment. In this paper, we employ the three dimensional viscoelastic finite element model of Xianshuihe fault and its surrounding region to explore the relation between fault slip rate and stress field, even the seismic distribution difference, according to the optimal boundary condition. And finally...

... as the initial stress condition for local analysis. The calculation model for pilot excavation is shown in Fig. 8, and the excavation depth is 30 m. Isotropic M-C criterion is adopted in numerical calculation for local excavation. Displacement boundary conditions: upper bound- ary is set free in the in-situ...
