SOLUTIONS FOR PREVENTIVE SAFETY IN THE GOTTHARD BASE TUNNEL

Philippe Favre

Open publisher page 1 citations

Abstract

The market for tunnel safety equipment is a very creative one. Powerful ventilation, detection, lighting, signalling and redundant power supplies are on offer and all highly efficient, at least in theory. The real difficulty for the design engineer lies in building a reliable, coherent system in which all individual devices interact with each other in a predictable and controllable manner. Past incidents have shown that even in state-of-the-art tunnels, this is not always the case. This paper describes the solutions adopted for the design of the technical equipment in the longest railway tunnel in the world, the 57 km long Gotthard Base Tunnel, which is now under construction. For the covering abstract see ITRD E114957.
