Rock masses in general contain various types of discontinuities such as joints, bedding planes and faults and have different deformational behavior because of the structural anisotropy caused by these discontinuities. When there exists a fault zone ahead of the tunnel face and a tunnel is excavated without perceiving its existence, it will cause stress concentration in the region between the tunnel face and the fault zone because of the influence of the fault zone on the arching phenomena. Because the underground structure has many unreliable factors in the design stage, the prediction of a fault zone ahead of the tunnel face by monitoring plans during tunnel construction and the rapid establishment of appropriate support system are required for more economical and safer tunnel construction. In this study the impact assessment for behavior of tunnel by fault zone is studies, a provided the method for more economical and safer tunnel construction.
