STRESSES BELOW EXISTING STRUCTURES DURING TUNNEL EXCAVATION USING TUNNEL BORING MACHINE (TBM) (140132)

DOI :

Abstract : The Finite element (FE) analysis include the response of structures t o horizontal & vertical dynamic forces and consider all site characteristics,such as soils and geologic conditions. The induced stresses under the foundation of adjacent buildings during newly constructed underground tunnel through TBM,were investigated in this study. Results of this study were examined to find out whether the amount of variations in forces and stresses are in the allowable ranges or not. In this paper,soil parameters used for the study are based on the existing Delhi Metro tunnel site. Using these soils parameters,tunnel excavation through TBM has been modelled in PLAXIS Tunnel - 3D and the adjacent structures have also been included in the model.
