We study the ground state properties, potential energy curves and potential energy surfaces of the superheavy nucleus 270Hs by using the multidimensionally-constrained relativistic mean-field model with the effective interaction PC-PK1. The binding energy, size and shape as well as single particle shell structure corresponding to the ground state of this nucleus are obtained. 270Hs is well deformed and exhibits deformed doubly magic feature in the single neutron and proton level schemes.
