Havryshchuk V. Improving method of the linear surface drainage designing from road coverage

The dissertation presents a new solution to the topical issue of improving the method of designing surface drainage from road coverage. The mathematical model offered and is based on application of the parameter of moistening of coverage and viscid properties of liquid. The increase of efficiency of the linear surface drainage designing performed by the ground of analytical dependences for determination of the duration forming superficial flow and taking into account of the real form catchment surface. It was substantiated a new calculation parameter - the design width of linear catchment surface, which takes into account the longitudinal slope of the road. This parameter allows to promote efficiency of hydraulic calculations to 45% on local areas. Effective forms of tray cross-sections (V-shaped or elliptical) was proposed and her hydraulic parameters at partial filling was determined. An engineering method of hydraulic calculation of the linear surface drainage system for road pavement was developed, which allows to increase the validity of design decisions by refining the determination of surface runoff and time of reaching the tray systems. The method for calculating local treatment facilities for linear catchment basins was proposed. The typical recommendations of implementation for surface drainage depending on the conditions of the highway route and the typology of sanitary solutions were developed, which made it possible to justify the classification of sections of roads for their use. The assessment and feasibility study of the feasibility of the installation of types of surface drainage depending on the conditions of the highway route were performed.
