Mechanical Properties of Universal Segmented Tunnel under Different Geological Conditions during Construction
Publication: ICRT 2021
ABSTRACT
This paper takes the universal segmented tunnel structures in the Shanghai Metro lines as the research object. A three-dimensional shell-spring-contact model is established to consider both the longitudinal and lateral characteristics of the universal segmented tunnel structures. The mechanical properties of the universal segmented tunnel under different geological conditions are analyzed. The results show that the transverse deformation of the tunnel is larger than the vertical deformation for all the considered conditions. As the typical geological conditions change from clay to sand, the maximum transverse and vertical deformation of the tunnel decrease, as well as the principal compressive stress and the damage area of the tunnel segment.
