APPENDIX C Stress analysis of downstream tunnel of outlet works, Prineville Dam: Through: Head, Technical Engineering Analysis Section Subject: Stress analysis of downstream tunnel, outlet works, At your request, two proposed cross sections for the downstream tunnel of the outlet works, Prineville Dam, Crooked River Project, have been analyzed. Coefficients for bending moment, thrust, and shear in terms of unit internal crown radius and unit loading are given at the center line of the section for twelve points around one-half of it. Dimensions of the two shapes studied are given on Figures 1 and 3. Loading conditions and the coefficients for them are shown on Figures 2 and 4. H. Baya Phillips Ira E. Allen |
