Abstract：
Alpha decay half-lives of even-even superheavy elements are calculated in the framework of the effective liquid drop model using the combination of constant asymmetry shape description for the mass transfer and the effective inertia coefficient.We have tested this model in the range of Z=88—98 at first.Then we extend this model to the superheavy area of Z≥100. The comparisons between calculated half-lives and experimental data show that the effective liquid drop model is very efficient to describe the alpha decay process of even-even superheavy elements.
