Abstract

The Meninting diversion-spillway tunnel is a part of the Meninting dam project located in West Lombok District. The construction commenced in 2017; then, a series of severe Lombok earthquakes halted the construction for a while in 2018, where some landslides occurred around the site. This possibly caused rock masses around the tunnel to be sheared off during the earthquake events. The last earthquake events increased seismic parameters, increasing stresses around the tunnel. Thus, the stability of the tunnel decreased in terms of a strength factor. Although, the overall stability of the tunnel was still fine with a strength factor of around 2.5; the tunnel certainly requires more stability improvements for future similar earthquake events.
