Three-dimensional analysis of underground metro stations drilling using Tunnel Column

Due to the expansion of the population and the density of cities, the science of drilling is also increasingly considered in order to serve the inhabitants of metropolitan areas. Drilling operations overshadow the lands and structures around them, from this on both international and domestic levels, drilling practices have been examined from a technical and non-technical point of view. In this paper, introducing a history of drilling in Iran and the world and common methods of tunneling, a number of analyzes the modeling is presented in the Abacus program. These modeling methods are used to study the effect of using the column method in the tunnel and the preset method Zeresis is provided for meeting control. In order to validate the results, a similar elastic model was created with the model made by Faris and colleagues whose results are compared with each other.
