Problem. The use of road culverts is currently an effective and relatively cheap means of passing surface water under the body of the road embankment. The number of road pipes on highways in areas with different topography is approximately 1.4 pipes per 1 km of the route. Road pipes, depending on the cross section, can be round, rectangular, oval, elliptical, arched, polycentric. The following are mainly used on roads: round pipes - 87%, rectangular - 9%, the rest - 4%. Automated design systems are used to calculate the characteristics of water-permeable road pipes, for example, the GRIS_T program is used to calculate the flow capacity of small artificial structures. Also, a program for the calculation of culvert road structures of the UKRRVS according to Ukrainian standards is being developed. The program includes the calculation of storm runoff according to the formula of MA-DY/SoyuzDorProekt and melt runoff; calculation of perforated road reinforced concrete round culverts for operation in non-pressurized mode. The article describes the automation of the calculation of road rectangular culverts. Goal. It is proposed to automate the calculation of road reinforced concrete rectangular culverts. Methodology. The current methods for calculating the throughput of reinforced concrete road culverts have been used. Programming was carried out in the C# language using object-oriented programming. Results. Attention is focused on rectangular pipes. Approaches to the design of rectangular road pipes in the world and Ukraine are considered. Computer-aided design systems for road pipes were analyzed. At the moment, the production uses the program for the automated calculation of culverts GRIS of the company CRE-DO DIALOGUE. The UKRRVS program is at the development stage. A modern method for calculating road reinforced concrete rectangular culverts was considered. The issue of the methodology and algorithmization of this calculation, coding and interface support has been resolved. Practical value. An algorithm for ...
