Analysis of the Straight Creek Tunnel Pilot Bore Instrumentation Data
Instrumentation of the 8,400-ft (2,560 m) Straight Creek Tunnel Pilot Bore, in late 1963, 1964, and early 1965, represented a pioneering geotechnical undertaking with little precedent at the time. The program results were transmitted in a series of 11 interim reports, and a final report dated February 5, 1965. The reports included extensive information on rock deformation and associated support system loads in a tunnel in moderately-stressed rock of widely varying competence. The results were flawed by the inclusion of spurious data influenced by unrecognized instrument malfunctions, and by a generally ineffective reporting format. In the present report, the original data has been screened, selected data reprocessed completely, and the data reorganized into a consistent and useable format. The reorganized information, comprising some 40 percent of the total original data, is considered to be reliable, and suitable for design and general engineering applications.
