COMPREHENSIVE ANALYSIS OF THE SHAFT STRUCTURE OF THE DNIPRO METRO

Purpose. The construction of the Dnipro Metro, which today is characterized by high efficiency and widespread introduction new technologies, has proved need for predesign, design work. purpose scientific article to identify during complex analysis structure mine shaft its stress-strain state, was obtained numerical geodetic monitoring. Methodology. During № 16-bis prognostic calculations state were performed. To do this, a finite-element model built, in fully reflects geometric features shaft, load on it boundary conditions. Part comprehensive monitoring, carried out operation. works included measurement deformations both lining shafts sections workings, as well surface near houses along route area influence working workings. Findings. displacement force factors (normal forces bending moments) determined. Based these results, reinforcement elements (bored pile, cap beam, reinforced concrete ring beam) selected. value deformed from indicates insignificant displacements designed structure. horizontal vertical recorded, caused public transport heavy vehicles. But values reached 1 … 2 mm, their effect buildings structures within normal limits. Originality. A comparison accuracy calculation. Practical value. results Metro made possible carry test solution ensure strength stability bored piles.
