Description
Damage to nearby surface structures caused by excavation-induced ground displacements is a major concern during excavation of tunnels in congested urban areas. Hence, developing a reliable numerical model for predicting the possibility of damage to nearby structures is needed. This paper presents the details of a comprehensive 3D finite element model developed to study the induced structural distortions of adjacent structures due tunneling activities. The proposed 3D model used the newly develop shotcrete material model in Plaxis to model the reinforced concrete elements of the tunnel. Utilizing the developed FE model the characteristics of the soil-structure interaction were studied and the criteria for the safety of the structures were accordingly proposed.
