This manual was prepared by the U.S. Army Corps of Engineers and provides technical criteria and guidance for the planning, design, and construction of tunnels and shafts in rock for civil works projects. Specific areas covered include geological and geotechnical explorations required, construction of tunnels and shafts, design considerations, geomechanical analysis, design of linings, and instrumentation and monitoring. The manual emphasizes design, construction and an understanding of the methods, and conditions of construction essential to the preparation of good designs.
