Information × Registration Number 0214U002471, 0113U006231 , R & D reports Title Research of the deformed state of running tunnels constructions of Kiev metro on the area of transition from spondil clays to buchak sands. popup.stage_title Head Petrenko Volodimir Dmitrovich, Доктор технічних наук Registration Date 30-01-2014 Organization Dniepropetrovsk National University of Railway Transport named after Academician V. Lazaryan popup.description2 In the represented report the results of the conducted researches of finite-elements model of support which becomes deformed in the area of transition from clays to sands are resulted. Such researches are executed: 1) the algorithm of calculation of the support deformed state which becomes deformed with the surrounding ground array is developed; 2) the finite-element model of deformed support in the area of transition from clays to sands is developed; 3) the calculations of variants of contour deep interval tunnel are executed and the results of the deformed state of support in the area of transition are analysed; 4) prognostication of the support state, placed fully or is partial in the water saturated sands during its deformation under act of the vibration loading related to motion of underground passage trains, is executed; 5) influencing of vibrodeformations is appraised on deformation of the ground array and the methods of fight against them are developed.
