APPENDIX F.

Design criteria:

The stability factors and loadings used in the design of the spillway and outlet works were as follows:

[blocks in formation]

Weight of dry earth fill 120 lb. per cu. ft.
130 (for conduits, spillway inlet walls)

Weight of saturated

earth fill 135 lb. per cu. ft. Horizontal dry earth- 40 lb. per cu. ft.

fill load 1/ 43 (for conduits and spillway

inlet walls)

Horizontal saturated

earth-fill load 1/ 75 lb. per cu. ft. Weight of water 62.5 lb. per cu. ft. . Weight of concrete 150 lb. per cu. ft.

I] By equivalent fluid pressure theory

Design of all concrete structures was based on concrete of 3,000 pounds per square inch compressive strength at 28 days and a modular ratio of 10. Allowable working stresses in pounds per square inch for all concrete structures except pressure and horseshoe conduits, for which other steel tension and concrete compressive stresses were used under certain loading conditions, are indicated below:
