A tunnel construction facing high risk and being a major concern in the construction of underground structure especially for their stability and settlement. This dissertation study on the influence of various jack forces magnitude to the soiltunnel reaction especially on the tunnel lining behavior and induced ground settlement at various depth above the tunnel crown. In addition, this research also discuss on the tunnel’s global behavior in order to support the surrounding load. A series of soil-tunnel modelling were carried out using ABAQUS as a finite element method (FEM) software.
