Research of efficiency roller compaction during construction of the tunnel by finite element method (FEM)

Abstract


The stress -strain state of rock mass adjacent to the contour generation at various ways of lining construction to determine the effectiveness of the proposed construction of new technological schemes . In the study of software modules used PLAXІS i SOLIDWORS, that allowed us to consider the behavior of fastening elements in the elastic and plastic formulation. As variants of previous comparison, the typical scheme used precast concrete erection fixing , fixing scheme with precast concrete and seal construction scheme with the formation of geotechnical properties of soil adjacent loop tunnel. Analysis of the numerical solutions of the FEM has confirmed the high efficiency of the proposed method of construction of the tunnel.

Keywords
