TUNNEL VISION

This article describes a flexible new computer system, developed for the Channel Tunnel and London Ring Main, that could radically improve the analysis of tunnelling performance. This computerised management system has been developed by consultant Babtie Shaw & Morton, and is commonly known on site as the 'Tunnel Reporting System'. Its computer information and analyses can produce a wide range of key facts needed to aid strategic decisions, for example about: (1) tunnel boring machine delays; (2) the need for drastic machinery alterations; (3) ventilation difficulties; (4) supply train breakdowns or derailments; (5) crane problems at the access shaft. Babtie has applied the latest information technology to work rapidly through the massive data generated by tunnelling schemes, and it quickly summarises performance information in the form of coloured graphs and charts. Two different performance analysis systems hve been developed for TransManche Link to monitor the British side of the Channel Tunnel, and Thames Water for work on the London Ring Main. Individual tunnel drives are treated separately in both projects. Both weekly reports and long term trend analyses are produced. Although the systems have provided no dramatic new insights into tunnelling, they have improved confidence and the appreciation of where there are problems. (TRRL)
