Abstract

The modes of pipe roof technology implementation in order to stabilize the excavations on the "Javorova Kosa" and "Pod Vugles" Tunnels are described in the paper. Both tunnels are specific regarding their geological structure and geo-technical characteristics of the rock mass in which the excavations were performed as well as regarding the mutual distance of 50 m measured alongside the highway axis. The multiphase New Austrian Tunneling Method (NATM) was used for the excavations in weak rock/soil.
