Abstract: The αdecay potential barrier of the newly synthesized superheavy nuclei starting from 294118 and 291116 have been determined and their halflives have been studied with the Generalized Liquid Drop Model(GLDM) connected with WKB approximation and Royer’s formulae．The αdecay halflives of the nuclei belonging to the superheavy nuclei starting from 294118 and 291116 have been calculated．The calculated results are in agreement with the experimental data， which show that the α decay halflives of superheavy nuclei with the GLDM and Royer’s formulae can be applied in the studying on superheavy nuclei successfully．Finally， the halflives of Z=118 and 116 isotopes have been predicted， and the results suggest there may be some longlived superheavy nuclei for αdecay in those isotopes.
