Theα-decay half-lives of a set of superheavy nuclear isotope chains from Z=106 to 118 have been ana- lyzed systematically within the WKB method,and some nuclear structure features are found.The decay barriers have been determined in the quasi-molecular shape path within the Generalized Liquid Drop Model (GLDM)including the proximity effects between nucleons in a neck and the mass and charge asymmetry. The results are in reasonable agreement with the published experimental data for the alpha decay half-lives
