NUMERICAL METHOD OF DETERMINING THE EARTH SURFACE SUBSIDENCE RELATED TO THE IMPACT OF TUNNEL COMPLEX FOR SOIL
Abstract
The work is aimed at geotechnical prediction of the effects of construction of tunnel on the variation of stress-strain state of the soil massif, namely, the resulting subsidence of the ground surface. The work is performed both by numerical and analytical methods. As a result of this work, the authors developed a technique that allows to determine the settling of the earth's surface in the process of moving the tunnel-passage mechanized complex by the finite element method through the use of contact elements. For analysis of the received results the calculation of the subsidence of the earth's surface while advancing the tunnel boring mechanized complex for analytical methods. The calculation results obtained by numerical and analytical methods agree well with each other both qualitatively and quantitatively, which indicates the reliability of the calculated models and calculations.
