Abstract

The selection of tunnel construction is considered possible if you see the background of Indonesia with diverse mountainous topography. Buffer construction is one of the things that must be considered in tunnel construction because the buffer serves to hold the tunnel load so that it does not collapse. The method used in the construction of the Ijo Tunnel is the New Austrian Tunneling Method (NATM) method with the strengthening of tunnel stability one of which uses using Wiremesh. This research is intended to provide safety factor information (safety factor) to strengthen tunnel stability using wire mesh by giving earthquake load or not. Analysis of calculations using the finite element method (finite element method) using Plaxis software. Based on the calculation results obtained the safety factor or safety factor of 2428> 1.25 (Bowles, 1984). Furthermore, the use of Wiremesh adds a safe number value of 0.076 to the tunnel stability.
