AbstractAbstract
[en] In excavating the underground cavern into the soft rock, it is not clearly known how the various permeability parameters with geological formation and the influence of excavation are affected to the stability of underground cavern and the seepage issues. Applying the elasto-plastic strain-softening model for coupled hydro-mechanics interactive problem, the numerical studies on the stability of underground cavern are discussed. In practical, the numerical analyses are performed considering permeability and b-value which controls with dilation. Then, the influence of permeability and volumetric strain to the stability of underground cavern is discussed. (author)
