Аннотация:Load Love coefficients are calculated for different rheological models of Venus. A static approach is used, for which two loadlevels are considered: the surface load (the planetary relief) and anomalous density variations located at depth. The planetis modeled as an elastic, self-gravitational body, while the density, elastic modulus and shear modulus being dependent onthe radius. The calculations have been performed up to the spherical harmonic degree and order 70, based on the accuracyof the gravity field at the moment. Several types of rheological models of Venus are considered. As a first approximation, wetake an elastic model (Model A). In the second case (Model B) we assume the presence of an elastic lithosphere. Beneaththe lithosphere there is a softened layer, which partly lost its elastic properties. Spreading till the core, softened layeris characterized by a reduced (to one-tenth of the initial value) shear modulus. In the third model (Model C) the shearmodulus is changing gradually: one-tenth of the initial value of shear modulus just beneath the crust is increasing up to itselastic value at the core-mantle boundary.
