The suppressive effect of the nonmagnetic doping on the high- Tc superconductivity has been studied based on the BCS-van Hove mechanism. Taking into account the bilayer coupling and three-dimensionality effects, we generalize the van Hove scenario into the multiband BCS model and calcu-late the relation between the transition temperature and the chemical potential. The results obtained are in good agreement with the experiments.
