| 英文摘要 | Owning to its special geological origin, columnar jointed rock mass is a special kind of geological structure with strong discontinuity and anisotropic. In this paper, influence of structural effect on the equivalent modulus of columnar jointed rock mass is discussed via Jointed Finite Element technique for the Baihetan project. It is noted in this paper that on the transverse plane, more the irregularity of the column is, the higher the equivalent modulus is. And this trend also aggresses with the increase of the column size. Columnar joints rock mass can be regarded as isotropic in the transverse plane. As the joint stiffness linearly increase, the equivalent modulus corresponding basically with the linear increasing. As for the longitudinal plane, more the spacing of the joint set II, the higher the equivalent modulus is. The equivalent modulus reaches its maximum value when the stagger ratio is 50%. Like on the transverse plane, as the joint stiffness linearly increase, the equivalent modulus linearly increase, correspondingly. The results of this paper agree well the existing field observations and 3-d numerical studies. The findings and conclusions of this paper may provide a reference for future studies. |
