Abstract
The nature of ice cover failure technology implemented with amphibian hovercrafts (AHC) is represents generation of a wave system in an ice cover under the effect of moving load on the ice cover. If gravity wave in water accompanies flexural wave in an ice plate, this combination of waves will be called flexural gravity wave (FGW), the speed of moving load υc equal to the speed of FGW propagation will be called critical. However, during the implementation of ice breaking works by single (AHC), AHC’s parameters may appear insufficient for failure of the ice cover of specified thickness at specific ice conditions. In these cases, efficiency of ice breaking works may be increased by simultaneous use of several hovercrafts, i.e. by interference of FGWs generated by hovercrafts. This work is dedicated to research of the ice cover deformation during the motion of several (paired) loads over it. a comparison of the theoretical and experimental data obtained confirmed the operability of the selected criterion for the failure of the ice cover, which allows it to be used to develop practical recommendations for use FGWs generated by several loads to failure the ice cover. Original results obtained.
