Foundation Deformations Modeling in Underworking and Hydroactivated Rocks

The use of piles with an adjustable operation mode to restraint the shaft sinking systems’ supporting structures

“…In case of uneven settlements of grillages piles, distortions of the lowering support ring and jamming of the drilling machine of the shaft sinking system occur [3]. Such phenomena are caused by changes in physical and mechanical properties and are similar to technogenic processes occurring during the formation and development of sinkholes on the earth's surface [4]. According to the studies [5], the main characteristics of soils that affect the risk of failure are their moisture content and strength characteristics: specific adhesion and angle of internal friction.…”

Prediction of deformations in the subsiding soils of Eastern Donbass’ undermined areas

“…The geotechnical and technogenic conditions of Eastern Donbass feature the commonness of subsiding loess soils and undermining of industrial areas prone to waterlogging [4]. The three mentioned factors (Figure 1) have a negative impact on ground facilities due to nonuniform vertical and horizontal deformations of the Earth's surface [12][13][14][15].…”

“…A combination of these negative factors is characteristic of some urban industrial areas in Eastern Donbass (Shakhty, Novoshakhtinsk, Gukovo, Zverevo, Krasny Sulin, Belaya Kalitva, etc.). Condition surveys [13,14] and analysis of dilapidated housing in the mining towns of Eastern Donbass indicate the relevance of this problem and the need for a method that could predict the geotechnical processes caused by the set of geological and technogenic factors.…”
