ACCOUNTING OF THE VARIABLE RESISTANCE OF CONCRETE AT AN EARLY AGE DURING THE MODELING OF LINING VERTICAL SHAFTS
Abstract
The combined technological chart for building of vertical shafts is analysed. The influence of strength properties of hardening concrete on interactions of the system «timber – massif» is explored by means of numerical simulation. The recommendations on perfection technology for timbering of deep shafts with a purpose of providing the durability and non-repair maintenance of shafts in the process of their exploitation are offered.
