FEM Analysis of Twin Tunnel Deformation Behavior Under Static Loading
Tunnels can be employed for a variety of functions, including railway tracks, highways, sewage, gas pipelines, transportation, and military ones. The construction of undergrounds passages can be an effective alternative in the modern era. But it is very important to keep the tunnel structure safe from the deformation. In this paper, an attempt is made to analyze the deformation behavior of twin tunnels under the effect of static loading conditions with the help of Finite Element software, i.e., ANSYS. Also, various factors which effect the deformation of twin tunnels are identified. The primary objective of the study is to check the deformation of tunnels at three different locations along the tunnel axis. In numerical modeling, the spacing between the twin tunnels models is varied as 1.5D, 2D, and 2.5D, where “D” is the diameter of the tunnel. Plaster of Paris is selected as the model material for making the geometry of the tunnel model. From the results, it may be concluded that deformation of twin tunnels largely depends upon the spacing between the two tunnels. The maximum deformation value is obtained when the spacing between the tunnels is less, and the deformation will reduce as the spacing between the tunnels keep on increasing.
