Abstract

To improve the quality of an ice core, it is necessary to investigate the probable causes of its stability loss. In this paper, we mainly study the affects accompanying thermal drilling, thermoelastic stresses. The influence of solid inclusions in ice, such as debris or rock fragments at the bottom of the glacier, on thermoelastic stresses is also presented.

A number of questions under consideration relate to both thermal and mechanical drilling. These are the stability of an ice core as a pivotal construction and the estimation of thermoelastic stresses in an ice core under its raising on glacier surface.
