STABILIZING METHODS FOR HIGHWAY CUTS IN LANDSLIDE-PRONE REGION

A highway was planned to pass through a landslide-prone region by excavating the bedrock. The bedrock consisted mainly of tuff, mudstone and sandstone of Tertiary age which are notorious for easy to slake materials. Many landslides have taken place in the region. During construction, a small slide took place on a cut slope, then a large slide occurred. As temporary measures, counterweight fill was placed on the foot of the slope. Detailed field investigations and stability analyses were carried out, and seven plans for permanent measures were proposed. Based on the stability considerations, earth removal work together with anchored walls was adopted and drainage wells were also constructed. (A) For the covering abstract see IRRD 873033.
