Abstract: The calculation scheme and, accordingly, calculation dependences for a case of interaction of an isolated structure and ice cover which is locate between this structure and a coast is improved. The case is considered, when the ice cover is between an extended coast and isolated structure. On the other hand structure of an ice cover is not present, that results in temperature displacement free, not contacting with a structure edge of ice. The extent of an ice cover in a direction to perpendicular effort is not limited. The structure impedes with temperature expansion not only opposite of a strip of an ice cover, but also sites, next to it. The scheme of interaction is given a fig. 1. It is obvious, that loading on such structure will be much greater, than on a coastal structure. The mechanical properties of polycrystalline ice are described by the reological model of an elastic-viscous body (Ivchenko, 1990). The ice cover is considered as a plate from a modeling material.
