AS-BUILT GEOTECHNICAL REPORT: ITS USE FOR DESIGN OF SUPPORT FOR THREE ROCK STATIONS, WASHINGTON, D. C. METRO
The three rock station areas have been explored by crown pilot tunnels and an as-built report, with geologic maps and sections, has been prepared for use by the design engineer as the basis of design for support of the structures. The geotechnical report describes the geologic structure in detail and relates it to excavation and support of the three crown pit tunnels and the running tunnels which will be enlarged to create the stations. The information was complete enough to permit the design engineer to visualize the geologic structure, compute loads for the various types of rock conditions, and design the steel set supports.
