Влияние тектонических нарушений на напряженно-деформированное состояние горного массива с подземными выработками

Abstract

The influence of tectonic fractures on the stress-strain of rock massive is considered. The main method of solution is finite element method. Tectonic breaches are modeled by using special type of contact elements – contact spring. Firstly it is considered the case when stress in massive are caused only by gravitation. Comparison of that stress with stress in undamaged massive was carried out. It was stated that there is considerable difference between stresses in undamaged massive and massive with tectonic breaches. Then the stress-strain state of massive caused by both tectonic fractures and mined out space was considered. The qualitative analysis of rock state was carried out.
