Improving the effectiveness of anchoring underground structures in permafrost areas

A new method of anchoring underground structures in permafrost areas, utilizing full anchors whose locks are based on the property that dispersed frozen rocks can significantly change their firmness depending on temperature, is considered. A new condition of energy efficiency of the use of this meth...
