This paper describes the observational procedure of a shallow tunnel construction in landslide area. The purpose of this research is to develop a construction method to control the displacements of the landslide and the tunnel by long face bolts and early invert closure. The practical application is proven that the both methods of long face bolts and early invert closure are effective for the tunnel construction under such a difficult condition.
