Abstract

This research focuses on the analysis of rock stability in the St. Michael Tunnel, part of the Wachau railway in Lower Austria. The study area includes the entire tunnel and the surrounding rock slopes with Para gneiss alternations and Schists. Initial surveys were conducted to assess the original ground and to identify areas of potential danger due to open fissures and sagging ridge vaults. The tunnel and rock slops was divided into three sections for analysis, using rock mass classification methods such as RQD, GSI, and Q-System. Stability analysis of the rock slope was then performed using a combination of was program such as RS2 and Dips.

The research aims to provide valuable insights into the behavior of rock slopes and tunnels by utilizing analytical approaches and numerical simulation techniques to assess the interactions between a rock slope and a tunnel. The study utilizes the slip line theory to determine the range of influences caused by tunnel excavation and the minimum safe distance between the tunnel arch and the slip belt. The analysis considers various influencing factors such as tunnel radius, rock friction angle, sliding belt slope angle, and rock friction coefficient. The case study of the St. Michael Tunnel in Lower Austria serves to demonstrate the applicability of this research and aid in the design and construction of underground infrastructure projects.
