The structural design of the culverts was <br />accomplished through the use of the following aids. <br /> <br />(a) Computer programs <br /> <br />(b) A.C.I. Building Code (318-63) <br /> <br />(c) EM 1110-2-2902 (Design of Misc. Structures: Conduits, <br />Culve~ts, Pipes). <br /> <br />(d) C.M.P. manufacturer's load tables <br /> <br />(e) Water control gate manufacturer's catalogs <br /> <br />(f) New Mexico State Highway Department Standards <br /> <br />(g) A.R.E.A. Design Manual <br /> <br />The following unit weights and allowable unit stresses were <br />assumed for design purposes: <br /> <br />Concrete: <br /> <br />ft 3000 psi <br />fc 1050 psi <br />Vc 60 psi <br />fs 20,000 psi <br /> <br />Reinforcing <br />steel: <br /> <br />Soil: Weight-moist <br /> <br />saturated <br /> <br />121 Ib/ft3 <br />129 Ib/ft3 <br /> <br />10-02. Corrugated Metal Pipe-Arch Culverts. This type of pipe <br />would be used for two culverts: (l) the culvert under U. S. <br />Highway No. 50 at the right of Levee Station 358+00 and (2) the <br />culvert under the Arkansas branch of the A.T. and S.F. Railway at <br />the right of Levee Station 394+75. Four concepts were considered <br />for these two culverts: <br /> <br />, <br /> <br /> <br />Int. frict. angle 320 <br />Allow. bearing 2000 psf <br /> <br />30 <br /> <br />L <br />
