SUMMARY NARRATIVE REPORT OF FHWA PROJECT 5B - TUNNELING

This report gives an overview of research conducted for FCP Project 5B, Tunneling Technology for Future Highways. That project was aimed at research including state-of-the art tunneling techniques unknown in the United States although accepted by other countries, and more experimental tunneling techniques not yet generally accepted. Specific research studies dealt with cut-and-cover tunnels, site investigation, earth movements, environmental criteria, and supporting activities (research conferences, information exchange, etc.). The report summarized research on: costs, classical ground control techniques, slurry walls, tie backs, anchors andf grouting for cut-and-cover tunnels; planning of site investigations, direct mechanical measurement (pressuremeters, cone penetrometers, vanes, piezometers) of soil properties, and indirect measurement by sensing techniques (aerial photography, acoustic, seismic, and electromagnetic systems); prediction and control of ground movements including phenomenological study and development of lining techniques; guidelines for the environment including air movement and pollution, tunnel lighting, traffic operation, driver behavior, safety and fire hazards.
