| Abstract: | By using the rock cores from the geological investigation in Three Gorges Project, the actual condition of rock acted by tensile-shear stress is simulated in this paper. The tensile shear properties of the rock including the uni-axial tension strength, the combined tension-shear strength, the stress-strain relation, and the failure criterion and failure mode are studied. Many valuable data and information are given to the construction of the Three Gorges Project. |
