Mohannad H. Al-Sherrawi [4] | Adnan F. Ali | Mohammed Najm [10]
Abstract: This study is conducted to demonstrate the ability of the 3-D representation of the underground reinforced concrete tunnels with the action of the method of construction. Three distinct objectives are considered, the methodology of idealization based on finite element representation, the nonlinear behavior of the system, and the effect of using interface element to represent the soil structure interaction. This study contains models of the materials, some notes about the used elements, and finally the simulation of two case studies with some results. Some of the conclusions that extract from this study are, negligible differences in the results were appearing from analyzing different F. E. meshes of the tunnel, and more conservative simulation for the model can be made by using interface element to simulate the soil structure interaction because it increases the response (displacement and stresses) in tunnel lining.
