Abstract：Safe height(SH) is an important problem for rock mechanics when the stability of surrounding rocks of underground houses of a huge hydroelectricity power plant in Southwest is studied. The height between the discontinuity and the vault is defined as SH. The solution of this problem is of important significance for the design of support structure of surrounding rocks for underground houses economically and reasonably. The problem of SH is analyzed with catastrophic theory. On the basis of catastrophic theory，a catastrophic model with cusp point of SH is developed by using elastic mechanics theory，which is better to solve the problem in comparison with another solution developed from structural mechanics.
