, the change law of pore water pressure, volumetric moisture content and transient saturated zone in slope example under the condition of design rainfall scheme was studied by the combination of laboratory field test data with actual climate condition based on saturated-unsaturated seepage theory. The results show that the pore water pressure and volumetric moisture content in the depth of the slope......
in Ref. [10-14]. Considering the effect of seepage pressure, analytical solutions of ground stresses and displacements for deep circular tunnel in saturated ground are derived by LI et al [3], however... of plastic zone and stress distribution surrounding a deep circular tunnel, but none of them have made it possible to allow the interaction between seepage pressure, lining and grouting as well as rock......
, respectively. Rcmax can be determined by uniaxial compression tests with loading perpendicular to the anisotropic plane of saturated rock, while Rcmin can be determined by uniaxial compression tests when..., to the foliation planes at the axial and diametral test [19]. Rc is determined from a uniaxial compression test on saturated intact rock samples through different loading directions with anisotropic......
of roadway near surface surrounding rocks and the release of elastic deformation energy of deep surrounding coal and rock mass are immanent causes that lead to the impact instability of roadway.... This suggests that the displacement of roadway corresponds to the release of stress and energy in the deep coal and rock. The above studies indicate that the combination of mining induced dynamic and static......
