【 摘 要 】

Algorithm of hydraulic calculation in steel culverts design with a normal and a spiral corrugations form is developed on the model hydraulic studies basis of corrugated metal culverts. Processing of experimental data was allowed to determinate flow coefficients, resistance coefficients, roughness coefficients; depths on an inlet to a pipe and on an outlet from it; critical depth; a critical bias and normal depths for different operation modes. Algorithm can be used for correction of calculations in normative documents, in new and reconstruction of the operating culverts design and for urgent relining of the damaged culverts.
